Q: Does Axis support the HTTP 1.1 Keep-Alive header?
A: The HTTP 1.1 specification makes mention of a Keep-Alive header to minimize the overhead associated with opening and closing HTTP connections.
In practice, the Keep-Alive feature is not particularly valuable in a corporate setting because of proxy servers.
Users wishing to use the Keep-Alive header should use the <noWiki>org.apache.axis.transport.http.CommonsHTTPSender</noWiki> class in conjunction with the Jakarta Commons HttpClient package.
