clientSetKeepaliveFlag()

void clientSetKeepaliveFlag

(

ClientHttpRequest *

clientSetKeepaliveFlag() sets request->flags.proxyKeepalive. This is the client-side persistent connection flag. We need to set this relatively early in the request processing to handle hacks for broken servers and clients.
