Property Value


A value that determines how ASP.NET caches URL metadata. The default value is 1 minute.



An example of URL metadata is information in the Web.config file about security restrictions that apply to a particular URL.

The following values have special meanings:

  • "Infinite". URL metadata is cached without a sliding expiration. This means caching continues until the server uses the maximum allotted amount of memory. This is the default behavior in ASP.NET 3.5 and earlier versions.

  • "00:00:00". URL metadata is not cached. The metadata is regenerated with every request. This is more efficient for scenarios where the same URL is rarely requested.
