annotate src/core/ngx_connection.c @ 647:95d7da23ea53 release-0.3.45
nginx-0.3.45-RELEASE import
*) 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 and 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.
