LoggingHttpClient ----------------- You can wrap a HTTPClient with the LoggingHttpClient to log all requests generated. This can be accomplished by:: HTTPClient client = HTTPFactoryFinder.createClient(new Hints(Hints.HTTP_LOGGING, "True")); Or as a system propety:: java -Dorg.geotools.http.logging=True .... All messages goes through the regular channel, and you will get the url requested. And if you turn on FINEST you can get the content sent in a POST or the content of the response.
