There is no specified limit client->proxy when the client accesses multiple sites The limits are there to prevent unintentionall congestion and unfairness. Both of the server resources and network. But yes, it's frequently a problem for certain types of sites, and the workaround of using multiple sitenames isn't exactly clean. I would propose adding a way where the HTTP server can grant it's clients to use more than 2 connections. > Furthermore the requirements that the second part places on a proxy > would greatly increase the complexity of the proxy, since it would then > have to > start multiplexing requests from different client connections over the > same server > connections. Why? The proxy is allowed to open two times the amount of client connections it sees with requests for the site. In reality this means that the proxy do not need to bother much about the limit unless it's proactively opening connections to a server or not pooling idle proxy<->nexthop persistent connections for reuse but randomly distributes client requests on many workers each with their own set of next-hop connections...
