nginx-0.1.38-RELEASE import
*) Feature: the "limit_rate" directive is supported in in proxy and
FastCGI mode.
*) Feature: the "X-Accel-Limit-Rate" response header line is supported
in proxy and FastCGI mode.
*) Feature: the "break" directive.
*) Feature: the "log_not_found" directive.
*) Bugfix: the response status code was not changed when request was
redirected by the ""X-Accel-Redirect" header line.
*) Bugfix: the variables set by the "set" directive could not be used
in SSI.
*) Bugfix: the segmentation fault may occurred if the SSI page has more
than one remote subrequest.
*) Bugfix: nginx treated the backend response as invalid if the status
line in the header was transferred in two packets; the bug had
appeared in 0.1.29.
*) Feature: the "ssi_types" directive.
*) Feature: the "autoindex_exact_size" directive.
*) Bugfix: the ngx_http_autoindex_module did not support the long file
names in UTF-8.
*) Feature: the IMAP/POP3 proxy.
