quick help needed...

after searching and searching I found this redirect.cgi script, all I have to do is enter

http://www.mysite.com/cgi-bin/redirect.cgi?http://anothersite.com/id2442/faf

the only problem I have is when I redirect it to another http://www.anysite.com it works fine but when I try redirecting it to a longer url without like the one above it says

Error: Your URL sould be begining by http:// or ftp://

the problem is it does start with http:// but I am guessing its checking the full url and maybe its too long or it doesnt have a .com at the end. Is there any way someone can help me edit or take out so it wont check for the redirecting url? here is whats in the file to edit... thanks!!
