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 CommonsHTTPSender (see FrontPage/Axis/AxisCommonsHTTP). Http keep-alive is the default behavior of CommonsHTTPSender : there is no special configuration nor coding instruction to add.
