David Hausladen updated VFS-316:
--------------------------------
Attachment: PREEMPTIVEAUTH.patch
adds setPreemptiveAuth method to HttpFileSystemConfigBuilder and consumes it in
HttpClientFactory. Permits streamlined auth for cases when throughput is
important.
> HttpFileSystemConfigBuilder needs option for preemptive authentication

>
> 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.
