RE: Extended ASCII characters used for injection

You'd be blocking legitimate usage of many different character encodings
including UTF-8 and ISO-8859-1 if you blocked 0x77 - 0xff.

Subject: Extended ASCII characters used for injection

Hi list,

I have a web app and I want to block special characters in URL on the
web server. Do you know if there is a risk of injection (XSS...) with
extended ASCII char (%7f-%ff)?
Is there any reason to block these characters?

Thanks
Regards,
Nib
