We are currently working on a very simple Webapp, and we would like to "obfuscate" ( what would be the right term? ) or encode somehow the request parameter, so we can reduce the chance an idle user from sending arbitrarily data.
For instance, the url looks like /webapp?user=Oscar&count=3
We would like to have somthing like: /webapp?data=EDZhjgzzkjhGZKJHGZIUYZT and have that value decoded in the server with the real request info.
Before going into implementing something like this ourselves ( and probably doing it wrong ) I would like to know if there is something to do this already?
We have Java on the server and JavaScript on the client.
