nginx: src/http/modules/proxy/ngx_http_proxy

annotate src/http/modules/proxy/ngx_http_proxy_upstream.c @ 505:ee66921ecd47 release-0.1.27

nginx-0.1.27-RELEASE import *) Feature: the "blocked" parameter of the "valid_referers" directive. *) Change: the errors while handling the request header now logged at "info" level. The server name and the "Host" and "Referer" header lines also logged. *) Change: the "Host" header line is also logged in error log. *) Feature: the proxy_pass_unparsed_uri directive. The special handling of the "://" symbols in URI, appeared in 0.1.11 version, now is canceled. *) Bugfix: nginx could not be built on FreeBSD and Linux, if the --without-ngx_http_auth_basic_module configuration parameter was used.
