We've just started using the Atlassian profiling servlet filter on a
project here, and have found it very useful. Thanks for releasing it as
open source!

There were two behaviours that didn't quite match our requirements:

1. writing of output to stdout - most app servers write a lot of
junk to stdout which makes it more difficult to parse and analyse the
profiling information
2. no capture of query string - in our case the request URI alone
wasn't sufficient to differentiate fundamentally different requests (we
needed to see the query string as well)

but thanks to the open source nature of the tool we were able to extend
the code to cover both of these requirements.

If you're interested, I've attached our updates to the code, just in
case you think this functionality would be worth adding to the official
distribution (I've attached both the full source as well as diffs
containing the changes). The new behaviours are all configurable via
filter parameters in web.xml, and the default behaviour of the filter
(when the new parameters are missing) is unchanged, so these
enhancements should be fully backwards compatible with v1.1.

My apologies if this isn't the correct channel for submitting changes -
I checked the site but didn't see any mention of an official submission
process.
