The most important WAO features include HTTP compression, ViewState optimization and CSS/Javascript optimization - all in one affordable package.
WAO significantly increases the response time for Web applications of all sizes. Most importantly, there is no need to modify the source code of your applications!

WAO ViewState optimization module removes the ASP.NET ViewState data from the rendered HTML code. It provides a performance boost for all types of ASP.NET applications. This module comes with four built-in providers - you can also develop a customized solution.

• Compression provider is used to compress the existing data and reduce the ViewState data size. The ViewState is not completely removed, but is much smaller in size.
• Cache provider is used to move the ViewState data from the rendered page to the ASP.NET cache.
• Disk provider is used to move the ViewState data from the page to server disks.
• SQL provider is used to move the ViewState data from the page to the SQL server.

WAO Page optimization / HTTP compression module allows ASP.NET applications to deliver compressed Web pages, reducing the required network bandwidth. WAO will compress dynamic and static content and cache it on the client-side. Server-side CPU load is reduced because most of the files will not be compressed repeatedly.
Features:

• Gzip and Deflate algorithms supported by all commonly used browsers
• Flexible provider model that lets you choose from several built-in providers or to create your own
• Fully configurable model (ability to exclude specific MIME types, ability to exclude specified application paths, ...)

WAO CSS and Javascript optimization module optimizes all CSS and Javascript files loaded by your ASP.NET applications. WAO will remove all unnecessary data from all satellite files.
Features:

• Caches the optimized CSS and Javascript files (using the file cache dependency)
• Removes all comments
• Removes all new line characters
• White space optimization
