Chapter 10 Transformed ApplicationsFeatures118 Application Gateway Administration Guide• Issues pages in transit while they are still being transformed, for lowerlatency.• Supports dynamic content, malformed and overlapping HTML, andlarge forms in HTML content.• Supports web pages that use any standard encoding and transcodesweb pages to the formats required by all supported devices.• Automatically removes content not supported by a device, such asJava applets and Flash programs.• Supports raw XML data sources through XSL transforms, allowing foropen standards and extensibility.• Supports advanced programming by allowing direct upload of XSLtransformations. XSL provides easy integration with existingtechnologies such as application servers, if needed.• For some IP phones, supports audio files that are in .au or .wav(PCM-encoded) formats. To match IP phone speaker characteristicsand conserve bandwidth, the Application Gateway converts audiofiles to 8-bit G.711 Mu-Law audio codecs sampled at 8 Khz.Data and Session ManagementThe Application Gateway data and session management features providedevice users with secure, efficient, and reliable connections. Thosefeatures include:• Works with any application server and any HTTP gateway (forexample, any WAP gateway), using standard protocols forcommunication. Requires no integration effort with existing systems.• Provides session persistence (stickiness).• Supports in-line operation. Using proxy ARP, the ApplicationGateway masquerades as the application server and transformscontent nonintrusively.• Supports session data (virtual cookies) for devices that do not nativelysupport cookies. The cookie is retained between the ApplicationGateway and the application server; the device user is not aware of thecookie.
