    I've been talking with Hackathology and he was having trouble understand the context of certain XSS attacks, so I decided to write him a quick PHP document which creates vulnerable variables and examples. The document has links which perform the injections on itself, I didn't have IE handy to test so forgive me if the IE examples don't quite work but hopefully they should.

    So if you're looking to learn how to protect your site against XSS or want to know how to perform pen testing then please download and run the document on a local testing server. Please don't run it on a live site because it obviously contains security holes. Note this document was intended for people learning, so any hardcore hackers will probably not find anything of interest.

    Hope it helps, download the document here:- XSS demos
