I look at your code, and it's fine, as you have one Webdav client associated with each thread. I think the problem is that the WebdavResource uses some static fields, which need to be removed. Thanks for the code, that will help me fix the issue. There's something strange in your traces : the traces in the httpclient refer to an older version. I must have made a packaging mistake ... (That means I'll release a fixed 1.0.12 really soon) Remy
