Its happening on pages that redirect.  For example:
whatever.cfm?UID=%24%24%24%2BXW0%20%20%0A&RUID=%24%24%24%2BXW0%20%20%0A and
that page would automatically redirect to 
whatever2.cfm?UID=%24%24%24%2BXW0%20%20%0A&RUID=%24%24%24%2BXW0%20%20%0A  

Thats when the url encoding issue comes in.  It has a problem with the url
variables in the redirect.


whatever2.html?UID=%24%24%24%2BXW0%20%20%0A%26RUID=%24%24%24%2BXW0%20%20%0A
