session_cache_limiter

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

Description

string session_cache_limiter ( [string cache_limiter])

The cache limiter controls the cache control HTTP headers sent to the client . These headers determine the rules by which the page content may be cached . Setting the cache limiter to nocache , for example , would disallow any client-side caching . A value of public , however , would permit caching . It can also be set to private , which is slightly more restrictive than public .

In private mode , Expire header sent to the client , may cause confusion for some browser including Mozilla . You can avoid this problem with private_no_expire mode . Expire header is never sent to the client in this mode .

הערה: private_no_expire was added in PHP 4.2.0dev.
