nginx 0.7.34 *) Feature: the "off" parameter of the "if_modified_since" directive. *) Feature: now nginx sends an HELO/EHLO command after a XCLIENT command. Thanks to Maxim Dounin. *) Feature: Microsoft specific "AUTH LOGIN with User Name" mode support in mail proxy server. Thanks to Maxim Dounin. *) Bugfix: in a redirect rewrite directive original arguments were concatenated with new arguments by an "?" rather than an "&"; the bug had appeared in 0.1.18. Thanks to Maxim Dounin. *) Bugfix: nginx could not be built on AIX.
