Merge r1526189, r1658765 from trunk.

r1526189 | trawick | 2013-09-25 16:29:02 +0200 (Wed, 25 Sep 2013) | 8 lines

mod_proxy: Add ap_connection_reusable() for checking if a connection
is reusable as of this point in processing.

mod_proxy_fcgi uses the new API to determine if FCGI_CONN_CLOSE
should be enabled, but that doesn't change existing behavior
since the connection is currently marked for closure elsewhere
in the module.


r1658765 | ylavic | 2015-02-10 18:25:54 +0100 (Tue, 10 Feb 2015) | 4 lines

mod_proxy_http: Use the "Connection: close" header for requests to
backends not recycling connections (disablereuse), including the default
reverse and forward proxies.
