nginx-0.3.13-RELEASE import
*) Feature: the IMAP/POP3 proxy supports STARTTLS and STLS.
*) Bugfix: the IMAP/POP3 proxy did not work with the select, poll, and
/dev/poll methods.
*) Bugfix: in SSI handling.
*) Bugfix: now Solaris sendfilev() is not used to transfer the client
request body to FastCGI-server via the unix domain socket.
*) Bugfix: the "auth_basic" directive did not disable the
authorization; the bug had appeared in 0.3.11.
