retrieve real target links from redirects

[hanyaz]

hello
I got a page where links are all redirects, i want to have the real link before going and visiting the target page. Is there a script that can help me to do so ?
My links look like that :
http://example.com/links/jump.cgi?ID=4615

Thanks in advance
Hanyaz

That is not a redirect link. Its a link to a script. There is no telling what that link might do.

[phranque]

that could possibly be the url of a script that externally redirects to another url.
if that were the case, you could capture the response to determine what the redirection url is.
you could do this with various tools such as the Live HTTP Headers add-on in FF, or the lwp-request command line tool, or a perl script using the LWP::UserAgent
and HTTP::Request perl modules...
