KeepAlive Directive

Top - Docs - General - Server - Resource - Access - FAQ - Tutorials

Purpose

In normal HTTP transactions, the browser opens up a separate connection to the server for everything the browser wants. So, if you have a page with 5 inline images, the browser will use separate connections to get the page and each inline image. With a browser which supports KeepAlive, the browsers requests the documents one at a time through the same connection. This eliminates the start up time and cost of each connection.
