annotate src/imap/ngx_imap_handler.c @ 641:5e8fb59c18c1 release-0.3.42
nginx-0.3.42-RELEASE import
*) Feature: the "bind" option of the "listen" directive in IMAP/POP3
proxy.
*) Bugfix: if the same capture in the "rewrite" directive was used more
then once.
*) Bugfix: the $sent_http_content_type, $sent_http_content_length,
$sent_http_last_modified, $sent_http_connection,
$sent_http_keep_alive, and $sent_http_transfer_encoding variables
were not written to access log.
*) Bugfix: the $sent_http_cache_control returned value of the single
"Cache-Control" response header line.
