any chance support for cookies would be added again?
The next release of davfs2 will have very simple support for cookies. It is in the CVS-sources and the release is almost ready, but needs testing. Because of this there is not yet a release date; I assume within the next month.
As neon still has no cookie support, I had to do it by hand. So I restricted to the most simple case: davfs2 accepts just one cookie. This should catch cases, where the cookie is used as session-ID.
It would be great, if you could test it. If you do not like to build the package from the CVS-sources, I would like to send you a prerelease package. What would be of help too, is any information about what kind of cookie support specific servers need.
