Hi Jairo, My best guess is that the site us using double encoded characters in the URL.

I receive a 500 error (as below): 500 Internal Server Error - The request was rejected by the HTTP Security filter. Contact your ISA Server administrator. (12217) Internet Security and Acceleration Server Ok, ISA found that a security issue (as the URL is a bit large, has encoded chars (%xxxx) and is a redirecting, etc, etc)... But, is there a way to get a rid of it? (Just curiosity. But I think: if it someday will happen on a 'useful' link :-)) Thanks Jairo --- Outgoing mail is certified Virus Free.
