Subject:    PropFindMethod failure in WebLogic Cluster

We are unable to work with the PropFindMethod when we cluster two slide
instances in Weblogic.
Rest of the WebDav methods seem to be working fine, however we get a
SocketTimeoutException when we try the PropFindMethod. Seems like the
request.getInputStream call is timing out. This works fine if the Webdav
client is talking directly to the individual node.

We are pursuing to see if it's a weblogic issue, however the strange
thing is if we test with a simple servlet that serves a http call, it is
able to retrieve the body of the request using the
request.getInputStream.

Has anyone encountered this issue? It happens both in Slide 2.0 and
Slide 2.1
