thanks for the response,

yeah I thought I probably got the MIME types thing a bit confused, so I guess the MIME type just tells the type of document right, i.e. the content type. "There is no necessary correlation between a URL and the content type it serves." ok I got that, but unfortunately I still have my problem...

you see i'm trying to find out the different technologies that are used on different sites, i.e. the number of sites using Perl/PHP/ASP, I can tell this by the file extension, i.e. index.php or index.pl or index.asp etc, so if I just send a request for http://www.google.com/ how can I get the extension of the file it returns...? I just need to get the filename of the returned file, or something like that, if anyone knows a better way to do this great :-)

I hope that made my question a little clearer, thanks again!

btw, is it true that Perl is the only programming language that looks the same before and after RSA encryption?! :-)
