Rewinding of the read buffers may be needed when doing HTTP PUT or POST
(or PROPFIND) with multi-pass authentication methods.
Depending on the HTTP server, the read buffers may or may not need
rewinding. (Apache returns a 401 error immediately before any data has
been read from the buffers, while Lighttpd doesn't reply until all data
has been sent.)
