HTTP / 1.1 indicates that persistent connections should be used by default. I am wondering if the web development server supports ASP.NET. So far I have seen that although the HTTP request contained
Connection: Keep-Alive
the answer contains
Connection: close
which causes the browser to close the connection after the request, and then use pipelining. This is not a big problem, but there is one interesting drawback, which is that the browser performs a DNS lookup before each request, which significantly increases the page load time.
This is best seen in Firebug (on the "net" tab).
