Max-age is the maximum absolute time a document is allowed to exist before being considered stale.

The SetMaxAge method does not use sliding expiration and will fail if the expiration date violates the principle of restrictiveness.

The following code example demonstrates how to set the Cache-Control: max-age header to 0 hours, 30 minutes, and 0 seconds.

No code example is currently available or this language may not be supported.
TimeSpan ts = new TimeSpan(0, 30, 0);
get_Response().get_Cache().SetMaxAge(ts);

var ts : TimeSpan = new TimeSpan(0,30,0)
Response.Cache.SetMaxAge(ts)
