System.Web.HttpCachePolicy.SetOmitVaryStar Method

Specifies whether the response should contain the vary:* header when varying by parameters.

Syntax

public void SetOmitVaryStar (bool omit)

Parameters

omit
true to direct the System.Web.HttpCachePolicy to not use the * value for its HttpCachePolicy.VaryByHeaders property; otherwise, false.

Remarks

This method allows you to prevent the output ached from adding a vary:* header to the outgoing response when the cached response varies by parameter. This is useful for clients varying caching by query string because most clients will automatically vary by query string without requiring the vary:* header.

Note:

The use of the vary:* header can disable all client caching.

This is a convenience method to affect the HttpCachePolicy.VaryByHeaders property. Passing true to the method directs the System.Web.HttpCachePolicy to ignore the * value for the HttpCachePolicy.VaryByHeaders property.

HttpCachePolicy.SetOmitVaryStar(bool) is introduced in the .NET Framework version 3.5. For more information, see The .NET Framework 3.5 Architecture.
