nginx 0.8.33
*) Security: now nginx/Windows ignores trailing spaces in URI.
Thanks to Dan Crowley, Core Security Technologies.
*) Security: now nginx/Windows ignores short files names.
Thanks to Dan Crowley, Core Security Technologies.
*) Change: now keepalive connections after POST requests are not
disabled for MSIE 7.0+. Thanks to Adam Lounds.
*) Workaround: now keepalive connections are disabled for Safari.
Thanks to Joshua Sierles.
*) Bugfix: if a proxied or FastCGI request was internally redirected to
another proxied or FastCGI location, then $upstream_response_time
variable may have abnormally large value; the bug had appeared in
0.8.7.
*) Bugfix: a segmentation fault might occur in a worker process, while
discarding a request body; the bug had appeared in 0.8.11.
