nginx 0.7.45
*) Change: now the "proxy_cache" and the "proxy_cache_valid" can be set
on different levels.
*) Change: the "clean_time" parameter of the "proxy_cache_path"
directive is canceled.
*) Feature: the "max_size" parameter of the "proxy_cache_path"
directive.
*) Feature: the ngx_http_fastcgi_module preliminary cache support.
*) Feature: now on shared memory allocation errors directive and zone
names are logged.
*) Bugfix: the directive "add_header last-modified ''" did not delete a
"Last-Modified" response header line; the bug had appeared in 0.7.44.
*) Bugfix: a relative path in the "auth_basic_user_file" directive
given without variables did not work; the bug had appeared in
0.7.44.
Thanks to Jerome Loyet.
*) Bugfix: in an "alias" directive given using variables without
references to captures of regular expressions; the bug had appeared
in 0.7.42.
