(PHP 4 >= 4.0.3, PHP 5)

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

Note: 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). 

Example 1. session_cache_limiter() example


/* set the cache limiter to 'private' */

$cache_limiter = session_cache_limiter();

echo "The cache limiter is now set to
$cache_limiter<br />";

Subject: 'Page can not be displayed' when hitting the
back button 
I have a shopping cart that is working completely fine
in Firefox. In 
I can not get the page to display when hitting the
back button. This 
may not
necessarily be a PHP problem, but since moving to PHP
session variables 
not cookies, this error has popped up.
In Firefox, I get the "POST DATA" message stating that
post data has 
been sent, blah blah blah. In IE, I get the "Page Can
Not Be Display".
I am just curious if anyone else has come across this
and if they found
