nginx 0.3.45
*) Feature: the "ssl_verify_client", "ssl_verify_depth", and
"ssl_client_certificate" directives.
*) Change: the $request_method variable now returns the main request
method.
*) Change: the ° symbol codes were changed in koi-win conversion
table.
*) Feature: the euro и N symbols were added to koi-win conversion table.
*) Bugfix: if nginx distributed the requests among several backends and
some backend failed, then requests intended for this backend was
directed to one live backend only instead of being distributed among
the rest.
