Jean-Marc Borer commented on VFS-428:
-------------------------------------

Not sure HC3 and 4 can coexist: WebdavProvider inherits from HttpProvider. If the latter uses HC4, it will probably break the webdav provider which relies on Jackrabbit which in turn requires HC3. Tricky issue.

> The deeper Problem is, that the HttpClient using by VFS does not append a trailing slash and mod_dir of httpd has "DirectorySlash On" per default. So httpd send 301 redirect to the same url with / appended.
> I know that for this reason of problematic webdav client apache introduced "redirect-carefully" for some user agents using the "BrowserMatch" directive. So I just tried adding the following into my <Directory> directive
> {code}
> BrowserMatch "^Jakarta-Commons-VFS" redirect-carefully
> BrowserMatch "^Jakarta Commons-HttpClient/3.0" redirect-carefully
> BrowserMatch "^Jakarta Commons-HttpClient/3.1" redirect-carefully
> {code}
> Its needed to have Jakarta-Commons-VFS *and* Jakarta Commons-HttpClient because of two requests from commons vfs using two different user agents.
> But instead of solving the issue, I get for every FileObject.getChildren() call at least one FileObject of type imaginary with the same basename as the parent. Thats not a problem at all (besides that this is totally wrong!) but deleting a parent just dont work anymore, because of an *non-existent* imaginary file inside the dir which cannot be deleted of course.
> To cut a long story short, what is the right httpd webdav server config to use 2.0 Release version of VFS?
