Preface As the name suggests, the File Cache to memory cache is to convert the data stored in the file to the memory, so that disk operations can be converted to memory operations, which can greatly improve the data access speed, and distributed deployment of cache data.

The role of Refresh_pattern:Used to determine how long a page stays in the cache after it enters the cache. Refresh_pattern only works on a page where the backend does not have a expires expiration, such as a forum page, and does not work on pages similar to Apache Mod_expires. Grammar:Refresh_pattern [-i] regexp min percent max [options] Several concepts:Resource age = Time the object entered the

Normally, the browser caches the page. In this case, you can access the page just after exiting. For example, you can access the page just cached after exiting, in some cases, this is not safe enough. The solution to the problem is as follows: Response. setheader ("cache-control", "No-Cache"); // forces caches to obtain a new copy of the page from the origin serverResponse. setheader ("

I. Overview The cache idea can be applied to all layers of software hierarchy. It is an internal mechanism that is imperceptible to the outside world. The database itself has a cache, And the persistence layer can also be cached. (For example, Hibernate also has cache levels 1 and 2) The business layer can also have a cache
