Re: Crash under Windows

I've sussed this one out.  Basically in Linux, atoi(NULL) returns 0, 
while in Windows, atoi(NULL) gives an access violation.  I've hacked a 
solution which stops it crashing, and returns 0 (the old behaviour).  It 
seems to be the result of a badly formed header.  Though, I don't know 
what the correct response code should be in this situation.

So this should go on someones todo list. HTTP.c: 730, 747
