nginx 0.6.18 *) Change: now the ngx_http_userid_module adds start time microseconds to the cookie field contains a pid value. *) Change: now the full request line instead of URI only is written to error_log. *) Feature: variables support in the "proxy_pass" directive. *) Feature: the "resolver" and "resolver_timeout" directives. *) Feature: now the directive "add_header last-modified ''" deletes a "Last-Modified" response header line. *) Bugfix: the "limit_rate" directive did not allow to use full throughput, even if limit value was very high.
