The Tomcat URI normalization process censors ";" and replaces some char sequences such as "//" with "/" resulting in mangled information being forwarded through request.getPathInfo(). The uncensored information is available through request.getRequestURI() however.

This task is to implement a custom HttpServletRequestWrapper which overrides getPathInfo() so that it returns the uncensored path information.

For example, given a request something like:

http://my.node/mn/object/http:%2F%2fsome.id%2Fof;interest

where the identifier is "http://some.id/of;interest", the normal tomcat request.getPathInfo() returns:

/object/http:/some.id/of

compressing "//" to "/" and truncating at ";"

The value returned by request.getRequestURI() is:

/mn/object/http:%2F%2fsome.id%2Fof;interest

So basically what is needed is to:

1. remove the servlet from the front of the path
2. urldecode the remaining info
3. return the result.
