Public Sub SetExpires ( _
   ByVal date As DateTime _
)

[ C# ]
public void SetExpires (
   DateTime date
);

public: void SetExpires (
   DateTime date
);

[ JScript ]
public function SetExpires (
   date : DateTime
);

date

The absolute DateTime value to set the Expires header to.

This method will fail if the expiration date violates the principle of restrictiveness.

The following example sets a cache expiration of 300 seconds from the time the page initially loads.

Response.Cache.SetExpires ( DateTime.Now.AddSeconds ( 300 ) );

Response.Cache.SetExpires ( DateTime.Now.AddSeconds ( 300 ) )
