Please refer to this resource for details regarding the official venues for contributions to the Apache Software Foundation: http://www.apache.org/foundation/contributing.html If you want to contribute code to the Jakarta HttpClient project, you are very welcome to subscribe to the httpclient-dev list and discuss the best ways to help with the HttpClient development on that list Cheers, Oleg On Thu, Aug 04, 2005 at 10:10:53AM -0400, Zhaohua Meng wrote: > Oleg, > > Thanks for the prompt response.
