XML / ASP / Encoding ??

I am working on a search engine that parses XML feeds and return search results. I was trying to achieve some kind of encryption to make (for example) this:

http://www.site.com/results.asp?keyword=mp3&url=http://www.findwhat.com/find.dll?ad=1&aff=4343&red=1&dir=1123


look like this:

http://www.site.com/results.asp?arg=jkdjfhjdghfhghhfghf6e8732473kjfddk jfdkj38783837jhfjdh7344387ujdhfdhfhdjfdjfhdjfhdfhd jf

while achieving the same results (redirecting to the correct site) and possibly incorporating information related to session id and other session variables in the string after arg=


To understand it more, compare overture.com or ispcheck.com search results with epilot.com (the hyperlink examples above are what you would see when you right-click and select Copy Shortcut on any of the search results).

Thank you

So you want to know how to encrypt the URL first? Just create a string with the query string params, such as

blah.aspx?that=1&this=myname&fom=333

then run one of the .NET plain-text encryption alrogithms over it. From the search page, just decode it and use split to grab the values as name/value pairs...
