void clientSetKeepaliveFlag ( ClientHttpRequest http)

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.

void clientSocketRecipient ( clientStreamNode node,

StoreIOBuffer  receivedData 

Write a chunk of data to a client socket. If the reply is present, send the reply headers down the wire too, and clean them up when finished. Pre-condition: The request is one backed by a connection, not an internal request. data context is not NULL There are no more entries in the stream chain.

void clientUpdateStatHistCounters ( const LogTags logType,

The idea here is not to be complete, but to get service times for only well-defined types. For example, we don't include LOG_TCP_REFRESH_FAIL because its not really a cache hit (we tried to validate it, but failed).
