An HTTP Module for ASP.NET that provides functionality to implement data compression techniques supported by most modern browsers. These techniques can be used to greatly improve the speed of data transfer across the Internet by reducing the amount of data that needs to be sent. This can greatly improve the viewing experience of your visitors by making your web pages load faster. A quick summary of the advantages is below. Bandwidth savings - You can expect ASPX pages to be reduced to about 1/3 of the size. Fast page loading - The major delay in loading pages is the time taken to transfer the HTML from the server to the browser. So a page light on graphics may load 3 times more quickly. Even graphics heavy pages will load their basic layout faster. Configured per site - Access to the IIS manager is not required. Web service resposne compression
