Google is your friend :)

MSDN Article: HttpResponse.AddHeader Method

You can also use HttpResponse.AppendHeader, which is semantically the same as HttpResponse.AddHeader.

Good Luck.

You can use this code in Page_Load

Response.Headers.Add("Expires", "ddd, dd m YYYY hh:mm:ss GMT");

You have to change the date for yours
