Hi guys, It's not a big deal (as I really don't need to access these sites), but since I'm using ISA 2004 in a test server, all URLs I receive as an advertising from my ISP to access an online store (periodically I receive this stuff from them), I can't get access using the URL they sent me. 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.
