ETagFix alters the IIS etag that is generated for each page so that it does not change each time your server is restarted. Etags are a method of informing web browsers and crawlers when a web page has changed. Using etags, your web browser or crawler will determine when a cached page may be used and when the page must be downloaded to present the current information. Sounds simple and useful, right? Well, yes and no. True, it's important for browsers to download a page when it really has changed. However, it's not necessary to take the time and bandwidth required to download a page when the etag has been updated due to restarting the web server, but the page information hasn't changed. EtagFix stabilizes the etag that Internet Information Services (IIS) generates so that it doesn't change each time the web server is restarted. Before a web page is downloaded by a web server such as IIS or Apache, the page sends out an etag to help the browser determine if the page has changed since the user last visited it. Each etag contains a unique ID generated by the web server. When the browser determines that the etag has changed, the page is downloaded again. Normally, changes in etags are not a problem. However, IIS changes the etag each time the web server is restarted, which means the visitor will be required to download the page again-even if the information has not changed. Downloading the page wastes time and bandwidth. ETagFix ensures that IIS does not change your web page's etag when the server is restarted. Stabilizing the etag means a reduction in the amount of bandwidth used, especially if your web site has several pages. And, since the more bandwidth a server uses to operate, the more expensive it is to run. By reducing bandwidth, ETagFix also saves you money!
