The Only Solution For Content Negotiation For IIS Servers

Serve Up Right & Relevant Pages to your Visitors


Transparent Content Delivery

Our PageXchanger content negotiation IIS module transparently delivers the best variant of the same resource to requesting browsers, thus making your site always relevant and usable to your visitors. Different languages, file types, content encodings, and character sets can be automatically delivered to different browsers based on preferences you set.

XHTML Compatibility

Content negotiation is the preferred method for serving XHTML in the most standards-compliant manner possible, while maintaining full support for downscale browsers.

Language Negotiation

Deliver the same page in multiple languages, with content served up appropriately based on the user's default language settings in their OS or Web browser.

For example you could simply set the URL as /myfile.htm, then create separate language files (i.e. /myfile-fr.htm for French, and so on), set your language list in the Language Negotiation tab, and the content negotiation between the server and the client's preferences ensure that the reader receives the page in the correct language.

Format Negotiation

  • Standards-Compliant XHTML -- XHTML, client-side XML and other advanced technologies alongside existing content safely and easily without implementing complex browser detection or rewriting the entire site.
  • Present multiple forms of images or other data (i.e .gif vs .png)

Easy Technology Migration

Migrate from one technology to another, say from ColdFusion to ASP.NET, faster, more reliably, and with complete transparency to end users.
