Log Message: |
mod_proxy_{http,ajp,fcgi}}: don't reuse backend connections with data available
before the request is sent. PR 57832.
ap_proxy_check_backend() can be used before ap_proxy_connect_backend() to try
to read available data (including from the filters), and is called by
ap_proxy_connect_backend() to check the socket state only (as before, still
relevant after ap_proxy_check_backend() due to filter data which may not have
triggered a real socket operation).
