Setting "option http-server-close" enables HTTP connection-close mode on the server side while keeping the ability to support HTTP keep-alive and pipelining on the client side.  This provides the lowest latency on the client side (slow network) and the fastest session reuse on the server side to save server resources.');

+	'descr' => 'Some HTTP servers do not necessarily close the connections when they receive the "Connection: close" set by "option httpclose", and if the client does not close either, then the connection remains open till the timeout expires. This causes high number of simultaneous connections on the servers and shows high global session times in the logs. Note that this option also enables the parsing of the full request and response, which means we can close the connection to the server very quickly, releasing some resources earlier than with httpclose.');
