Greetings, I am writing a Linux program under c++ that will eventually download the most recent episode to my mythtv backend (Yes, I deemed this easier than getting mythstream to work under minimyth). I figure ill run it as a cron job every week BUT when I send my http request:
GET /diggnation/feed/xvid-large/ HTTP/1.1\nHost: diggnation.com:80\nFrom: craftkiller@gmail.com\nUser-Agent: CraftCast/1.0\n\n
I get a 302 redirect back:

I put the link it sends me into my web browser to check it out and I get the revision 3 front page. Can someone tell me what I'm doing wrong? Even though this is entirely an HTTP issue ill attach my program's source code below (yes I used a c++ socket tutorial example to start it... so if you recognize it then you should remember your n00b days aswell... unless you wrote this tutorial... then you are AWESOME)
