Add a sitemap provider at runtime in asp.net (MVC framework)

I'm building a regionalized site each region has it own sitemap and own content. The regions can be added at runtime. Is there any way to add a sitemap provider at runtime?

I need multiple site map providers at once so that I can leverage the m开发者_运维问答vcsitemap without to many changes.

You can create your custom site map provider in order to take information from database or from another file than web.sitemap.

Example of database sitemap: http://msdn.microsoft.com/en-us/magazine/cc163657.aspx

There is an MVC sitemap provider available at: http://mvcsitemap.codeplex.com/

I'm using it for a project right now. It has caching functionality built into the code so your overhead shouldn't be too bad. Even in debug mode running the sitemap for every request takes < 100 ms so I wouldn't worry about performance.

Your performance concerns are a little yagni too. "Could be quite resource consuming". You don't know so your just prematurely optimizing.
