Asp tutorial. net provides three main forms of cache: page-level output cache, user control-level output cache (or segment cache), and cache api. The advantage of output cache and fragment cache is that it is very easy to implement. In most cases,

When cache is used, it is actually changed from response-> execution-> explicit delivery to response-> explicit delivery. The "execution" in the middle is saved and the efficiency is improved. There are generally four types of cache technology.I.
