Changes with nginx 1.0.11 15 Dec 2011v1.0.11

*) Change: now double quotes are encoded in an "echo" SSI-command
output.
Thanks to Zaur Abasmirzoev.

*) Feature: the "image_filter_sharpen" directive.

*) Bugfix: a segmentation fault might occur in a worker process if SNI
was used; the bug had appeared in 1.0.9.

*) Bugfix: SIGWINCH signal did not work after first binary upgrade; the
bug had appeared in 1.0.9.

*) Bugfix: the "If-Modified-Since", "If-Range", etc. client request
header lines might be passed to backend while caching; or not passed
without caching if caching was enabled in another part of the
configuration.

*) Bugfix: in the "scgi_param" directive, if complex parameters were
used.

*) Bugfix: "add_header" and "expires" directives did not work if a
request was proxied and response status code was 206.

*) Bugfix: in the "expires @time" directive.

*) Bugfix: in the ngx_http_flv_module.
Thanks to Piotr Sikora.

*) Bugfix: in the ngx_http_mp4_module.

*) Bugfix: nginx could not be built on FreeBSD 10.

*) Bugfix: nginx could not be built on AIX.

+    *) Исправление: строки "If-Modified-Since", "If-Range" и им подобные в
+       заголовке запроса клиента могли передаваться бэкенду при кэшировании;

+
+    *) Исправление: в директиве scgi_param при использовании составных
+       параметров.
