Add "Connection: close" to the HTTP request header, which tells HTTP/1.1
servers to close the connection after completion of the response. This should be compatible with HTTP/1.0, as HTTP/1.0 allows for custom header fields which should be ignored if not recognized by the server. With some server configurations, the server would keep the connection alive without this header line (despite the plugin requesting HTTP/1.0), resulting in the plugin running into either the server's or it's own timeout (reported by Roman Schliessmeyer and Jesse Morgan via IRC). git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1759 f882894a-f735-0410-b71e-b25c423dba1c
