Hi,
I have tested a cgi 'TestCgi.exe' on server and recive error from server:
HTTP 500 - Internal Error
Internet Explorer
Why?
For test I use this c source and compiled in .exe:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
puts("HTTP/1.1 200 OK\nContent-type: text/plain\n\nHello world!");
return 0;
}
My testcgi.exe is in folder absolute path:
'C:\Programmi\Abyss Web Server\htdocs\'
This is file abyss.config:
