The Cache Array Routing Protocol (CARP) is used in load-balancing HTTP requests across multiple proxy cache servers. Hypertext Transfer Protocol ( HTTP) is a Communications protocol for the transfer of information on the Internet. HTTP persistent connections also called HTTP keep-alive or HTTP connection reuse is the idea of using the same TCP connection to send and receive multiple HTTP requests responses as HTTP compression is a capability built into both Web servers and Web browsers to make better use of available bandwidth HTTP Headers form the core of an HTTP request and are very important in an HTTP response An ETag (entity tag is an HTTP response header returned by an HTTP/1 HTTP cookies, or more commonly referred to as Web cookies tracking cookies or just cookies are parcels of text sent by a server to a Web client (usually The referer, or HTTP referer, identifies from the point of view of an Internet Webpage or resource the address of the webpage (commonly the URL The following is a list of HTTP response status codes and standard associated phrases intended to give a short textual description of the status The HTTP response status code 200 OK is used to represent a successful response from the server as defined in RFC 2616 The HTTP response status code 301 Moved Permanently is used for permanent redirection The HTTP response status code 302 Found is the most common way of performing a redirection The 403 Forbidden HTTP status code indicates that the client was able to communicate with the server but the server doesn't let the user access what was requested The 404 or Not Found Error message is an HTTP standard response code indicating that the client was able to communicate with the server Hypertext Transfer Protocol ( HTTP) is a Communications protocol for the transfer of information on the Internet. It works by generating a hash for each URL requested. A different hash is generated for each URL and by splitting the hash namespace into equal (or unequal parts, if uneven load is intended) the overall number of requests can be distributed to multiple servers.

Implementations include Microsoft Internet Security and Acceleration Server and the Squid cache. Microsoft Internet Security and Acceleration Server (ISA Server is described by Microsoft as an " integrated edge security gateway " Squid is a Proxy server and Web cache daemon. It has a wide variety of uses from speeding up a Web server by caching repeated requests
