Hey Jim--
 
Any chance you've had a mo to find these RFCs? I've been looking for
them myself with no luck. If you could even just point me to the right
place, that would be great.
 
Thanks,
Rob

I literally hate these jerks that think adding XML or HTTP tags to a
query is valid web site programming!

The fact is, this is the most basic form of script injection.

 

I have some RFC's that give valid URL syntax - I'll fwd them later...

Hi all-- 

Sometime back I used Jim Harrison's VBS script to block script
injections (the StartOfTag (<) and EndOfTag (>) things). I've run into a
couple of legitimate websites that are now blocked by our firewall. Are
there legitimate reasons an HTML programmer would use these tags? I'd
like to at least sound educated when I contact the website folks to tell
them why I'm blocking them.

Thanks, 
Rob
