Subject [jira] Updated: (VFS-316) HttpFileSystemConfigBuilder needs option for preemptive authentication
Date Wed, 08 Sep 2010 20:12:34 GMT


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.

> 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.
