# session_cache_limiter

(PHP 4 >= 4.0.3, PHP 5)

session_cache_limiter -- Get and/or set the current cache limiter

## Description

string session_cache_limiter ( [string cache_limiter])

session_cache_limiter() returns the name of the current cache limiter. If `cache_limiter` is specified, the name of the current cache limiter is changed to the new value.

The cache limiter defines which cache control HTTP headers are sent to the client. These headers determine the rules by which the page content may be cached by the client and intermediate proxies. Setting the cache limiter to `nocache` disallows any client/proxy caching. A value of `public` permits caching by proxies and the client, whereas `private` disallows caching by proxies and permits the client to cache the contents.

In `private` mode, the Expire header sent to the client may cause confusion for some browsers, including Mozilla. You can avoid this problem by using `private_no_expire` mode. The expire header is never sent to the client in this mode.

> 참고: `private_no_expire` was added in PHP 4.2.0.

The cache limiter is reset to the default value stored in session.cache_limiter at request startup time. Thus, you need to call session_cache_limiter() for every request (and before session_start() is called).

예 1. session_cache_limiter() example

`<?php /* set the cache limiter to 'private' */ session_cache_limiter('private'); $cache_limiter = session_cache_limiter(); echo "The cache limiter is now set to $cache_limiter<p>"; ?>`

Also see the session.cache_limiter configuration directive.
