PageXchanger and content negotiation offer a new approach to web site content, source code, and even URLs by enhancing security, usability, and maintainability. This IIS Web server module separates content from the underlying Web technology, providing a powerful form of content negotiation so that Web sites can use cleaner URLs in source code and Web browser displays. Eliminate and hide accessed file types from the site visitor by enabling developers to remove any extension (.html, .aspx, .php, .gif, etc.) from source code, making your IIS-based Web sites and applications more secure (application layer masking), more friendly (file presentation based on browser and server preferences) and easier to maintain (faster migration to new technologies).With clean URLs, site security is strengthened by masking the technology a Web site was built upon from site visitors & potential hackers. Obscure your Web site's technology platform with PageXchanger to stop hacker exploits like direct URL guesses and source sifting.PageXchanger allows for multiple forms of content to be served automatically by separating content from underlying site technologies. Deliver the same page in multiple languages, with content served up appropriately based on the user's default language settings in their Web browser. Developers can present multiple forms of images or other data -- use PNG images, XHTML, client-side XML and other advanced technologies along side existing content safely and easily without complex browser detection or rewriting the entire site. Save time and money when you present persistent URLs in all company communications and avoiding annoying redirects or broken links. Migration from one technology to another, say from ColdFusion to ASP.NET, is also faster, more reliable, and completely transparent to end users.PageXchanger is fully COMPATIBLE with IIS 4/5/6 and Windows NT/2000/Server 2003 and is available for download with a 30 day full functional trial.
