> I find that the credential challenges produced by the WebdavFileSystem as it uses the HttpClient creates a great deal of superfluous HTTP traffic just to perform BASIC authentication.  In some scenarios, dumbed-down preemptive authentication is needed for swifter traversals of the repository.
> I suggest adding preemptive authentication to HttpFileSystemConfigBuilder and HttpClientFactory to address this problem.
