Custom HTTP request not returning expected results.

[szalinski]

Please can somebody tell me why this isn't returning the index page? It is technically supposed to, and if somebody can get it to work I can then use remote download resume functionality in my site. According to <link removed>, it is a HTTP 1.1 request that supposedly should work...I can't find any syntax errors! What's wrong?
