Ahhhh, I think I misunderstood some of what you said. The CGI script you are running is working just fine.. but you are saying that every time your CGI script accesses one of the links you would like to check, it's that link which is returning the invalid method headers, not the link you are accessing with your web browser. Hmmm....

Now we have an interesting question :-) After digging around the docs some, I don't immediatly see anything incorrect about your approach. But if I do, I'll be sure to post it. Sorry about the misunderstanding there :-) Good luck,
