I haven't found this explicitly covered. I apologize if it already is somewhere...
http://hc.apache.org/httpclient-3.x/dependencies.html shows : commons-codec 1.2 commons-logging 1.0.4 The latest released versions are: commons-codec 1.3 commons-logging 1.1.2 Looking at http://commons.apache.org/releases/versioning.html it sounds like HttpClient 3.1 can be used with minor version revisions of its dependent components and therefore with the latest releases shown above. Is that correct? Thanks, Henrich
