Managed applications that target the .NET Framework 1.1 and that use sockets when they communicate with HTTP 1.1 servers (for example, with Internet Information Services 6.0) open a new socket if the server sends an HTTP 304 ("not modified") response header with the Content Length: 0.
This behavior may cause application overload when the application can use the same socket that it initially used to communicate with the server.
