Subject RE: [users@httpd] Enabling CGI on Apache 2.2 on Mac OS X 10.6.4
Date Mon, 30 Aug 2010 16:19:13 GMT

Thanks, Bob.
I've never used perl, although it sounds interesting enough to start learning it. However,
on this occasion, I need to port an existing application written in C++ that connects to other
applications on different servers using TCP/IP sockets among other things, so I find it much
easier porting it across platforms rather than rewriting the whole thing on a different language.
It turns out I was erroneously setting the result line "HTTP/1.0 200 OK" instead of letting
Apache do so, as Nick has kindly pointed out. I'm now unstuck (if that is a word), and progressing
I do appreciate the time you've taken in answering me, though. Thanks again.
Take care,
