Remarks
The VaryByHeader is a semicolon-delimited set of headers used to vary the cached output. These are HTTP headers associated with the request. For more information, see Caching Multiple Versions of a Page.
Note
The VaryByHeader settings are the same ones used by the VaryByHeader
attribute of the @ OutputCache. Varying by all headers by setting the value of "*" is not recommended. It can result in cache overflow or a denial of service attack on the Web server.
