For sliding expiration, use this:

Cache.Insert(key, value, Nothing,
             Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(10))

For absolute expiration, use this:

Cache.Insert(key, value, Nothing,
             DateTime.Now.AddMinutes(2), Cache.NoSlidingExpiration)

You must use one or the other. From the Microsoft documentation at http://msdn.microsoft.com/en-us/library/05kd8d77.aspx

absoluteExpiration

... If you are using absolute expiration, the slidingExpiration parameter must be NoSlidingExpiration.

slidingExpiration

...If you are using sliding expiration, the absoluteExpiration parameter must be NoAbsoluteExpiration.
