KEMP Technologies, Inc. Web Switch
A web switch provides more targeted load balancing than Layer 4 only switches. Although Layer 4 switches can examine the TCP/IP port number and differentiate HTTP from FTP and SMTP traffic, Web switches can differentiate HTTP requests and send them to the appropriate servers for processing. For example, requests for HTML pages are switched to one web server, while searches go to another, and streaming media requests go to yet another. A web switch may also be known as an Application delivery controller, URL switch, Web content switch, content switch and Layer 7 switch. The Web switch is designed to provide improved load balancing for a website because different requests can be routed to the most efficient source for delivering their content.
