Webpage Counter
A webpage counter has been one of the first applications that were
created on the web. It counts the number of times that your webpage
was accessed.
Installing the counter
In the examples, few number of digits are used for simplicity,
however the counter can handle 80 digit long number.
How to call the program?
Insert the following code into your web page.
<img src=/cgi-bin/Count.cgi?df=yourdomainhere.com>
Yourdomainhere.com must be a domain that is hosted by Isterra.
How do I count individual page hits?
You can specify individual pages to be counted by putting a
dash and the pagename after your domain. For example.
<img src=/cgi-bin/Count.cgi?df=yourdomainhere.com-pageone>
and on another page
<img src=/cgi-bin/Count.cgi?df=yourdomainhere.com-pagetwo>
Following the examples are explantions of the extra options.
| simple,
no frame, digit style A (default) |
<img src="/cgi-bin/Count.cgi?df=yourdomainhere.com&ft=0"> |
 |
| frame
with default frame-color and thickness is 4 (specified) |
<img src="/cgi-bin/Count.cgi?df=yourdomainhere.com&ft=4"> |
 |
| A
hidden counter is here |
<img src="/cgi-bin/Count.cgi?df=yourdomainhere.com&sh=F"> |
 |
| No
datafile specified with df ,therefore, random digits
will be displayed |
<img src="/cgi-bin/Count.cgi?ft=0"> |

Parameter |
Name |
Description |
Default |
| expires=X |
This parameter can be used to
change the image caching behavior of certain web browsers. |
The integer value of expires
specifies the cache expiration duration time in seconds. If
you do not want the browser to cache the image, specify 0.
If you want the browser to cache image for 5 minues, specify
the value as 300. The valid integer range of the expires parameter
is between 0 and 604800 (7 days).
Note, these parameters will work with browsers that support
the HTTP Expires header as specified in HTTP specification.
By default, most web browsers cache the image received from
the counter. That means, if someone visits your page and
comes back after a while, the counter or clock does not
get refreshed. |
None |
| reload=B |
Count page reload if the site admin configured
the counter to support it.
(Added on: Dec-05-1998) |
If the site admin configured the counter to
count reload, users can choose to count reload (default) or
ignore reload. The site admin allows count reloading by yes,
1 or true in the [options] section of the configuration
file with the keyword count_reload. Note, if the admin
decided to ignore reload count (count_reload=No), user preference
is ignored. The valid values for the Boolean parameter reload
are Y, N, T, F, 1 or 0. |
reload=T
Count reload if site admin configured to so. |
| cdt=year ; month
; day ; hr ; min ; sec (Added on: Dec-13-1998) (no space) |
Show the countdown time to this target date. |
The parameter cdt specifies the countdown target
date. The valid values for this parameter is 6 integers separated
by semicolon. The first integer specifies the year, for example:
2000. The month starts at 1 (January). The first day is 1.
Note: in Unix systems, the year can not be less than 1970
as Unix epoch starts starts at 00:00:00 on January 1, 1970,
Coordinated Universal Time (UTC). The range of hr is 0 to
23. The range of min is 0 to 59 and the range of sec is 0
to 59. To count down to Year 2000, the parameter will be:
cdt=2000;1;1;0;0;0. If you do not specify any Timezone with
the parameter timezone, the countdown
will be calculated from the web server time. For example if
you like to show the countdown from GMT, specify timezone
as: timezone=GMT+0000. |
None |
| cdf=year ; month
; day ; hr ; min ; sec (Added on: Jul-17-1999) (no space) |
Show the countdown time from this date. |
The parameter cdf specifies the countdown from
date. The default is to calculate from the current local time
or local time of a specific timezone if the parameter timezone
is specified. The valid values for this parameter is 6 integers
separated by semicolon. The first integer specifies the year,
for example: 1999. The month starts at 1 (January). The first
day is 1. Note: in Unix systems, the year can not be less
than 1970 as Unix epoch starts starts at 00:00:00 on January
1, 1970, Coordinated Universal Time (UTC). The range of hr
is 0 to 23. The range of min is 0 to 59 and the range of sec
is 0 to 59. |
The local web server time. |
| sdhms=B |
Show the day, hr, min, sec in countdown or
not. |
This parameter affects how the countdown is
displayed. The valid values for the Boolean parameter sdhms
are Y, N, T, F, 1 or 0. By defualt, the value for this parameter
is True, that means the countdown is shows as Day, Hour, Min
and Sec. If you just want to show the countdown days, specify
F as the value. |
sdhms=T |
| sfd=B |
Show from date (sfd) below the countdown. |
The parameter sfd shows the from date below
the countdown. The from date is the time when the program
is executed. The time in date is always in 24 hr format. If
you use the parameter timezone, the
timezone offset will be shown at the end of time. It may be
necessary to see this date to make sure that the Counter program
actually ran and the browser is not loading the image from
cache. Use cache=F&expires=0
to make sure that browser does not cache the image. The valid
values for the Boolean parameter sfd are Y, N, T, F, 1 or
0. |
sfd=F |
| display=X |
Specifies what to display. |
The valid values for X is: counter,
clock, date, countdown, image
or version. If the value is countdown and if the countdown
time is not specified with parameter cdt,
the countdown to year 2000 is assumed. See also: cdt.
Note: If you specify display=image and if you specify a datafile
with df parameter and if incr
is true, then counter will be incremented in the datafile.
This will help some people who do not like to show the counter,
instead they can show an image. You can use incr=F
from another page to monitor the counter. |
display=counter |
| timezone=X |
Display time/date of the specified timezone. |
The parameter timezone= is only significant
with display=clock, display=date
or display=countdown Use this parameter
if you want to display time or date of another timezone or
calculate countdown in reference to a timezone to a target
date. The timezone must be specified with a negative or positive
four digit offset from GMT, for example: timezone=GMT-0500
or timezone=GMT+0000 or timezone=GMT+0530. The routine to
display time of various timezones are written in a generic
way. Therefore, the unix machines will not be aware of daylight
saving time because of the way the routine is written. For
example, if daylight saving time is on, to display time of
NY, the timezone will be timezone=GMT-0500 instead of timezone=GMT-0400.
If the clock displays your local time wrong, specify your
timezone with that parameter in order to display the correct
time. |
None. |
| tformat=X
|
Time format in 12 or 24 hour. |
This parameter can be used to display time
in 12 or 24 hour format. The valid values for the parameter
X is 12 or 24. |
tformat=12 |
| dformat=X |
Specifies date format. |
This parameter is only significant with display=date.
The valid value for the string parameter X is any combination
of MMDDYY (Month-Day-Year). For example, dformat=ddmmyy, dformat=YYMMDD.
To show the full year in the display instead of two digit
year specify YYYY instead of YY, for example dformat=MMDDYYYY.
To show full year you can also use the parameter fy. |
dformat=MMDDYY |
| fy=B |
Show the full year (fy) in the date instead
of only two digit year. |
This boolean parameter indicates whether to
show all the year digits instead of default two digits in
the date. By the way the program will display all the year
digits by default from Year 2000. The valid values for the
boolean parameter fy are Y,N,T,F,1 or 0. See also: dformat. |
fy=F |
| istrip=B |
Use of image strip On/Off |
The boolean value of istrip specifies whether
to use image strip or not. If you specify istrip=F, the program
will look for the individual digit image files in the digits/style
directory. The valid values for the Boolean parameter istrip
are Y, N, T, F, 1 or 0. |
istrip=T |
| ft=X |
Frame Thickness |
You can wrap the counter in an ornamental frame
of X pixels thick. Use 0 for no frame. Values over 5 make
a nice 3-D effect. |
ft=4 |
frgb=R;G;B
or
frgb=RRGGBB (in hex) |
Frame Color |
Specifies the color of the frame in RGB (red/green/blue)
format. Each color component, R, G, and B is specified as
a value between 0 and 255. If you use ft= without a frgb=
param, the default color is used.
If you specify a frgb= without a ft=, then the frame thickness
defaults to 5. All the examples show ft=5. The color can
be specified as hex string or a name. Do not use a # before
the hex string as Netscape. For example, if you want to
specify white in hex, use frgb=ffffff. You also can use
a color name (e.g. frgb=blue) if the counter is configured
to do so (look at the cfg file). Look at the color
name mapping database for some hints about color name
database. |
frgb=100;139;216 or
frgb=648bd8 |
| tr=B |
Transparency On/Off |
You can specify if your counter image will
have a transparent color with the Boolean B. So tr=Y means
there will be a transparent color. It does not matter if the
GIF files used for the digits are "transparent";
you must specify explicitly which color to make transparent.
If you specify a trgb=, then you do not need to specify tr=Y.
If you specify tr=Y and do not specify trgb=, then the default
color black will be transparent. The valid values for B are
Y, N, T, F, 1, or 0. |
tr=F
No Transparency |
trgb=R;G;B
or
trgb=RRGGBB (in hex) |
Transparency Color |
Specifies the color to be made transparent
in RGB (red/green/blue) format. Each color component, R, G,
and B is specified as a value between 0 and 255. If you use
tr= without a trgb= param, the default color is used. The
color can be specified as hex string or a name. Do not use
a # before the hex string as Netscape. For example, if you
want to specify white in hex, use trgb=ffffff. You also can
use a color name (e.g. trgb=blue) if the counter is configured
to do so (look at the cfg file). Look at the color
name mapping database for some hints about color name
database. If you use trgb= then tr=Y is not needed. |
trgb=0;0;0 or
trgb=000000 |
| md=X |
Max Digits |
Defines maximum number of digits to display.
Any value between 5 and 80 inclusive are permitted. Padding
with leading zeros is automatically done for you; longer counts
are truncated to the given X. |
md=6
Without padding |
| pad=B |
Left padding with 0s |
Turn padding on/off in conjunction with md=
setting. It also affects padding hour in clock. Valid values
for the Boolean parameter B are Y, N, T, F, 1, or 0. |
pad=N
Without specification
of a md=value pad=Y
With specification of a md=value |
| dd=A |
Digit Directory |
Denotes directory of a specific styles of digits.
Four styles of digits are supplied. They are kept at the directories
A,B,C and D respectively. Visit the digit
mania page for other styles of digits. |
dd=A
My green LED digits |
| image=gif_file |
Display this GIF file |
You can display any GIF image specified with
this parameter. The location of this file is determined by
the dd= parameter. Note that no path in the GIF file is allowed.
All attributes of the counter apply to the image. This parameter
is used for compositing counter image with the GIF image.
The default alignment is top-center and the default offset
is 2 pixels from the top of the GIF image. If you want to
composite clock, date or contdown, specify so with the display
paramter. |
None |
| comma=B |
Display comma after every 3rd digit from right. |
The boolean value of parameter comma specifies
whether to display comma after every 3rd digit from right.
If you use this parameter as true, the left padding with zeros
will be turned off. |
comma=F |
srgb=R;G;B
or
srgb=RRGGBB (in hex)
prgb=R;G;B
or
prgb=RRGGBB (in hex) |
Change a color of the image to a target color
on the fly. |
Any one color of the image can be changed to
a different color on the fly. srgb stands for source color,
that is the color to change. prgb stands for pen color, that
is the target color. The values for srgb and prgb can be colon
separated color components (e.g, srgb=255;0;0), a hex value
(e.g. srgb=ff0000) or a color name (e.g. srgb=red). The color
name can be used if you configured the counter to do so (look
at the cfg file). |
srgb=00ff00
(0;255;0 green)
prgb=00ffff
(0;255;255 cyan)
With chcolor=T |
| chcolor=B |
Change a color of the image. |
This parameter is usually used to change the
default green color to cyan. That is if you specify chcolor=T,
and you want to change green to cyan, then you do not need
to specify srgb and prgb parameters. 1x1 GIF is displayed.
The valid values for the Boolean parameter B are Y, N, T,
F, 1, or 0 |
chcolor=F |
| st=X |
Start Count |
This parameter is used to set the initial value
of the counter to some number X. This is only valid if you
decided to allow automatic datafile creation. It is a bad
practice to allow automatic datafile creation, however it
makes site maintaining easier. The automatic datafile creation
option is specified in configuration file and can be changed
at run time. Note that this parameter has no effect if the
datafile already exists. If you want to change the counter
value in a existing datafile, hand edit the file. The minimum
value for st is 1. |
st=1
Count starts at 1 |
| sh=B |
Show digits |
Used to turn display of digits on or off according
to the Boolean B. When sh=T, counter will be displayed and
incremented, this is the default behavior.
If sh=F no digits will show, but the counter will still
increment; instead of digits a transparent 1x1 GIF is displayed.
The valid values for the Boolean parameter B are Y, N, T,
F, 1, or 0 |
sh=Y |
| df=data_file |
Datafile to store count |
Specifies the name of the file for storing
the count in. The file must be allocated to you as was mentioned
in the "Authorizations" section above. You can use
df=random to display a random number.
One special use of the parameter is df=RANDOM. This returns
a random number using the fractional portion of the host's
time of day clock as a seed for the generator. Unlike all
other WWWcounter parameters, the file name provided is case-sensitive,
except for the value random. Or Random, or rANDOM, etc. |
df=random
if no datafile
is specified |
| incr=B |
Increment Count |
Makes it possible to display the current count
without incrementing the count. This can be used to examine
the count for reporting or other purposes without adding to
the count. Valid values for the Boolean parameter B are Y,
N, T, F, 1, or 0.
|
incr=T
Increment the counter |
| lit=X |
Display literal |
Makes it possible to display a given, predetermined
string. The valid values for the string X are digits, a,p,:
and - |
None |
| negate=B |
Negate the color |
Makes it possible to negate the color of the
counter digits. Note that the Frame is exempted from negating.
Valid values for the Boolean parameter B are Y, N, T, F, 1,
or 0. |
negate=F
Do not negate |
degrees=X
or
angle=X |
Rotate X degrees |
Makes it possible to rotate the counter image
X degrees. The possible values of X are 90, 180, 270 and 360.
Note 360 is meaningless as the counter will come back to the
original 0 degrees. Note: Microsoft
MS Explorer interprets °rees as the degree character
(it's gotta be a bug in IE), so use angle to be safe. |
degrees=270
With rotate=Y and without degrees=X
rotate 270 degrees
clockwise |
| rotate=B |
Rotate On/Off |
The Boolean value B turns on or off rotating.
If you use degrees= setting, rotate is not needed. Valid values
for the Boolean parameter B are Y, N, T, F, 1, or 0. |
rotate=F
Do not rotate |
| xy=x;y |
composite the counter image to a base image
at the location x,y |
When a base image is specified with image
parameter, the parameter xy can be used to composite the counter
image on the base image at location x,y. x is positive towards
right and y is positive downward. The co-ordinate of the upper
left corner of the base image is 0,0). See also: align. |
xy=1;1 |
| align=X |
composite the counter/clock/countdown image
with a base image and align the counter image. |
This option can be used to composite the counter
on a base image (specified with image
with known width and height. This way, you will be able specify
the width and height of the counter image in the <img src=
tag while calling the counter. The implication is, if the
counter is the first thing in a large table, the browser will
not have to wait to calculate the width and height of the
counter image before loading the rest. The valid value for
the parameter align is topleft, topcenter, topright,
midleft, midright, midcenter, bottomleft,
bottomcenter and bottomright. The parameter
offset can be used to specify the offset
in pixels from the edge of the base image. Note: xy
parameter has higher precedence than align. Therefore, if
both xy and align is specified xy will take the precedence.
See also: xy. |
align=bottomcenter |
| offset=N |
Offset of the counter image in pixels from
the edge of the base image while compositing the counter with
an image. |
The parameter offset is used with parameter
align to specify the offset of the counter
image in pixels from the edge of the base image while compositing
the counter/clock image with an base image. If align=topleft,
the the offset is counted from the top and left edge of the
base image. If align=topcenter, the offset is counted from
the top edge of the base image. If align=topright, the offset
is counted from the top and right edge of the base image.
If align=midleft, offset is counted from the left edge of
the base image. If align=midcenter, offset is ignored. If
align=midright, offset is counted from the right edge of the
base image. If align=bottomleft, offset is counted from the
left and bottom edge of the base image. If align=bottomcenter,
offset is counted from bottom edge of the base image. If align=bottomright,
offset is counted from the right and bottom edge of the base
image. The valid value for the paramter N is a positive integer.
See also: xy. |
offset=2 |
