If you have mod_perl available, you can get at the request headers via the $r->headers_in method. I don't think you can get at the exact request headers under mod_cgi. Most of the headers are mapped to the HTTP_XXX environment variables. Another alternative is to write a quick server, which you can do using the HTTP::Daemon module. This will let you grab the exact headers. If you are trying to write a client, you need to use the LWP family of modules, including LWP::UserAgent and HTTP::Request. Using these, you can construct the proper headers and requests without having to snoop what IE is sending. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
