>Release: 1.3b3
>Environment:
Windows NT 4.0 build 1381 Service Pack 2.
Visual C++ 5.0
Running with AMD 200 Meg Pentium-MMX, 64 Meg RAM and about 100 Meg free HD
space.
>Description:
A CGI program writen in C (instead of shell samle program provided withe the
server) which simply echo back all the environment variables supported by the
server.
The server runs the CGI my echo.exe program but sends "blank" for the
environment variable QUERY_STRING.
Your bug fix list about "POST" method used by MSIE 3.0X which gives an extra CR
LF and Apache server "eats up that extra CRLF does seam to be working under
Windows NT version server.
>How-To-Repeat:
Use following program - compile it. Use compiled program as a CGI program
call it as "echo.exe"
-----------------------[ program begin] ---------------
#include <stdio.h>
#include <stdlib.h>
void main(int argc, char *argv[])
{
printf("Content-type: text/plain\n");
printf("\n");
printf("SERVER_SOFTWARE = %s\n", getenv("SERVER_SOFTWARE") );
printf("SERVER_NAME = %s\n", getenv("SERVER_NAME") );
printf("GATEWAY_INTERFACE = %s\n", getenv("GATEWAY_INTERFACE") );
printf("SERVER_PROTOCOL = %s\n", getenv("SERVER_PROTOCOL") );
printf("SERVER_PORT = %s\n", getenv("SERVER_PORT") );
printf("REQUEST_METHOD = %s\n", getenv("REQUEST_METHOD") );
printf("HTTP_ACCEPT = %s\n", getenv("HTTP_ACCEPT") );
printf("PATH_INFO = %s\n", getenv("PATH_INFO") );
printf("PATH_TRANSLATED = %s\n", getenv("PATH_TRANSLATED") );
printf("SCRIPT_NAME = %s\n", getenv("SCRIPT_NAME") );
printf("QUERY_STRING = %s\n", getenv("QUERY_STRING") );
printf("REMOTE_HOST = %s\n", getenv("REMOTE_HOST") );
printf("REMOTE_ADDR = %s\n", getenv("REMOTE_ADDR") );
printf("AUTH_TYPE = %s\n", getenv("AUTH_TYPE") );
printf("CONTENT_TYPE = %s\n", getenv("CONTENT_TYPE") );
printf("CONTENT_LENGTH = %s\n", getenv("CONTENT_LENGTH") );
}
--------------------------[end of program] ----------------------------
On the client side use following HTML form to POST the form contents-
--- begin HTML ---------------------
<HTML>
<HEAD>
<TITLE>GGI Simple test</TITLE>
</HEAD>
<H1 ALIGN="CENTER">Welcome to CGI Test on Apache!</H1>
<FORM ACTION="http://your_server_name/cgi-bin/t3"; METHOD=POST>

</FORM>
------- end HTML --------------------
>Fix:
Most probable reason for theis problem is - Extra CRLF sent by MSIE to the
server between the POST method.
Your documentation some where says you have taken care of these "legacy"
problem by eating away the extra CRLF. However this fix is not working on
"Win-NT" server.
