ok, so I started over. now, the dll loads, and I can interact with it on the web, but for some reason, no matter what I try, I can't get more than the first 48k of post data, even though I'm sending about 80k.
the html file that contains the submission form is as follows:
Code:
<HTML>
<HEAD>
<TITLE>
Test Form
</TITLE>
</HEAD>
<BODY>
<FORM method="POST" action="/team_isapi/plain-isapi.dll?foo=bar">
<INPUT type="text" name="T1"><br>
<TEXTAREA name="T2" rows="10" cols="60"></TEXTAREA><br>
<INPUT type="submit" value="Submit" name="B1"><br>
<INPUT type="reset" value="Reset" name="B2"><br>
</FORM>
</BODY>
</HTML>
the only header file in the project is as follows:
Code:
// plain-isapi.h
#ifndef __PLAIN_ISAPI_H
#define __PLAIN_ISAPI_H
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
#include <vector>
#include <queue>
#include <httpext.h>
using std::endl;
using std::ofstream;
using std::ifstream;
using std::string;
using std::stringstream;
using std::vector;
using std::queue;
#endif // __PLAIN_ISAPI_H
and the main source file:
Code:
// plain-isapi.cpp
#include "plain-isapi.h"

I have been working on this one issue for about 4 hours now, with no progress. I'm sure it's something simple that I'm overlooking, but I just don't get it.
