nginx 0.6.4
*) Security: the "msie_refresh" directive allowed XSS.
Thanks to Maxim Boguk.
*) Change: the "proxy_store" and "fastcgi_store" directives were
changed.
*) Feature: the "proxy_store_access" and "fastcgi_store_access"
directives.
*) Bugfix: nginx did not work on Solaris/sparc64 if it was built by Sun
Studio.
Thanks to Andrei Nigmatulin.
*) Workaround: for Sun Studio 12.
Thanks to Jiang Hong.
