Hello; I am writing a servlet filter that decrypts parameter=value on the way in, and encrypts things on the way out.
I can find lots of things on the internet that say this is what servlet filters are ment to do.
I can get the request parameter/values then encrypt/decrypt the name-value pair.
I am missing how to swap out the old parameter name-value pair for the new parameter name-value pair in the request. I don't want to change my parameters to attributes, because so many other classes depend on getParameter.
