Can't use xwiki through an authenticating http proxy
Sorry for the late reply but I just found some time to try-out the latest xwiki release, seeing that the problem I had signaled a few weeks ago had been fixed.
However, it's not working for me.
I now get an HTTP 407 (authentication required) error in the log:
