CountServer
WWW Homepage Access Counter Server For OS/2 Warp
CountServer is a multi-threaded OS/2 HTTP server program that serves a GIF
counter image for your homepage. Being written as a standalone server
program, it caches everything in RAM and takes a much smaller percentage of
the CPU and disk resources on your server than CGI counter programs.
[CtServer Beta Release 1.9b01]
Release: May 27, 1996
Expires: Aug 1, 1996
Download: http://www.knowledgy.com/ctserver/
Requirements
* OS/2 Warp Connect or
* OS/2 Warp with TCP/IP Stack from Bonus pack or
* OS/2 Warp Server
Features
[*] Does not require server-side includes
Program runs with any Web server.
[*] Manage multiple counters
CtServer can now store and return multiple counters and their
values. Each counter is given a name and is passed in the URL.
Each counter also has the date of it's first hit stored. This
date can be returned as a GIF image.
[*] Parameters from either parameter file for passed on URL
Styles are created in the parameter file. Each of these styles
can specify any of the optional features. This way, you only have
to specify a counter like this:
"http://www.yourserver.com/cnt2"
Parameters can also be passed from the URL. A combination of the
two can be used, with the URL tags overriding the style tags.
[*] 3D Frame around digit image set to any color and any width.
This frame is optional and can be of any thickness from 5 to 50
pixels. The color of the frame can also be specified.
[*] Set maximum number of digits to display
The maximum number of digits is what limits the highest count. If
the maximum count is reached, a GIF message stating that the
maximum count has been reached is returned.
[*] Optional leading-zeros
[*] Set number of threads
The number of threads that are service client request can be
specified.
[*] Beep on incoming request
This optional feature makes the server beep every time a client
request for a page arrives. This is handy for testing or for
lightly loaded servers.
[*] Preset counter to any value
Any counter can be preset to any value from a web browser. This
feature password authenticated.
[*] Prevent counter from incrementing
A counter can be advanced on a hit without displaying. This is
done by returning a 1 bit transparent GIF.
[*] Create named styles with parameters
Named styles can be created in the parameter file with all the
parameters needed. This means that you only have to pass the
style name to return a counter, time, date, etc.
[*] Prevent passing of paramters on the URL
For closed servers that need protection, only the counters and
their parameters entered in parameter file as a style will be
returned.
[*] Store first hit date for each counter
The first time a counter is requested from a client, the date of
that first request is stored. This date can be displayed
automatically by returning a GIF either textually (e.g. Hits
since Apr 26:), or as a numerical date (e.g. 04-26-96).
[*] Prevent repeated counter incrementing
One of the problems with counting every time a client request a
page from a server is what happens it the client re-loads the
page. This a give an over-inflated count. CtServer can prevent a
counter from incrementing if the same client has re-requested the
page in less than a specified time.
[*] Return Time GIF
The local time of the server can be returned as a GIF image in
either 12 or 24 hour time.
[*] Return Date GIF
The local date of the server can be returned as a GIF image. A
format string can be used which specifies the actual format to
display the date (e.g. MDY, M-D-Y, DMY, etc,).
[*] Return random number GIF
A random number can be automatically generated and returned as a
GIF image.
[*] return literal number
A literal number can be passed on a format tag and returned as a
GIF image.
[*] Rotate image
Any of the returned GIF images can be rotated 90,180, or 270
degrees.
[*] Display all counter values
An HTML page can be returned which has the count and first hit
date of each counter currently stored by the server. This command
is password authenticated.
[*] Display all parameter file values
An HTML page can be returned which shows all the values in the
server parameter file. The values for each style is also
displayed. This command is password authenticated.
[*] Login and password protection
Some of the commands to the server, such as preset counter value,
are protected by a login name and password stored in the
parameter file. When one of these commands is requested, the
standard Web authentication mechanism is used.
[*] Multiple digit GIF images
The server comes with a collection of digit GIF images. Each
counter can use a different digit style. These digit GIFs are
loaded at server startup or when requested. This is one of the
features that makes CtServer so fast and take very little load on
the server. Each digit style has all the digit values stored as 1
GIF for compactness and speed. CtServer comes with a utility,
DMERGE which combines digit GIFs into 1 GIF for any digit GIFs
you may have downloaded from the Web.
