Compression

Today’s Web-based applications which are richer in their textual and visual content still run over the non-optimized HTTP protocol, which was originally designed for dial-up speed applications and one way transfers of data between two computers, and is therefore less efficient in dealing with the new types of multi-sequence and high bandwidth Web traffic. This “chatty” nature of HTTP and the growing volume of each transaction, due to the richer content, slows response time considerably and consumes expensive bandwidth.

A Radware hardware-based compression solution can ensure optimal application delivery and bandwidth savings, through compression of Web pages such as HTML and JavaScript in real-time before transmission on the network. This is important especially for small remote offices and home offices users where bandwidth may be limited. This dynamic HTML compression accelerates traffic by reducing the payload using an open compression standard (gzip and Deflate), providing a powerful performance boost since HTML is an ASCII text, which is highly compressible. The support of industry-standard gzip algorithm (as well the Deflate algorithm) ensures compatibility with virtually all popular Web browsers without requiring any special software installation on the end-user computer.

AppDirector offers options to control compression behavior. These capabilities include the ability to define whether objects should be compressed for Browser, Content-Type or URL specific behavior, and view and use Predefined exceptions of the default compression behavior based on known Browsers limitations.
