[ConfigurationPropertyAttribute("omitVaryStar", DefaultValue = false)]
public bool OmitVaryStar { get; set; }

Property Value

Type: System.Boolean

true if the vary header is enabled; otherwise, false. The default is false.

The vary header indicates the request-header fields that the server uses to determine which of multiple cached responses are sent in response to a client request. The default for the OmitVaryStar property is false. By default, ASP.NET sends the vary header in all POST requests, as well as in all GET-request query strings. If the OmitVaryStar is true, ASP.NET omits the vary header when returning the response for cached pages, provided that the GET request to a response is cached with no VaryByCustom property and the POST request to a response is cached with no VaryByParam property and no VaryByCustom property.

The following code example shows how to use the OmitVaryStar property.

// Get the current OmitVaryStar.
Boolean omitVaryStar =

// Set the OmitVaryStar.
outputCacheSection.OmitVaryStar = false;
