General Tips for debugging UrlRewriteFilter

Because every java web project is slightly different, debugging can be difficult. Try to:

Turn on debug logging (see filter params in manual).
Simplify the problem as much as possible. Perhaps make a new web application without other filters/servlets, try and replicate the problem there.
Use an HTTP debugger (such as fiddler) to check that what you think is happening really is.

If you think you have found a bug:

Read the source
Write a unit test that proves the bug, this reduce the amount of time it will take to fix the bug.
See issues list and add a new issue if necessary
