security - Anti XSS and Classic ASP

Question

I'm currently trying to secure my classic ASP application from XSS. I came across the AntiXSS from Microsoft on the net and I was wondering if this would work with a classic application?

If not do you have any ideas how I could go about sanitizing the strings?

Answer 1

To sanitize strings I would HTML encode all output, that way you don't have to dink around with special characters or huge regex expressions

Server.HTMLEncode(string) 

The two most important countermeasures to prevent cross-site scripting attacks are to:

• Constrain input.
• Encode output.
