Chashing

stephen

Is there a way to prevent cashing or a code that will refresh the page on the first load?

Scenario: On login the page changes slightly

I have been having a problem where you go to the page, it loads and then when you login and go back to that same page, it’s being built from memory. Can I have it set so it will refresh?

Thanks

I don't know what I’m smoking today but I meant to say caching

If you want to prevent a html-page from beign stored in cache, insert these two lines in your php source file.

header("Cache-control: no-cache");
header("Expires: " . gmdate("D, d M Y H:i:s") . " GMT");

You might have to remove old pages already stored in cache, or else the old ones are being used instead.

Hope this one makes it for you.

Thanks but I get this error

Warning: Cannot add more header information - the header was already sent (header information may be added only before any output is generated from the script - check for text or whitespace outside PHP tags, or calls to functions that output text)

bengan

All header information must be sent before any text is sent, i.e. the header tags need to be placed in the beginning of the php script.

Or you might use output buffering, but I lacks experience from that (but there´s some stuff about that on this site).

stephen

could it be the version of PHP I am using?

<?php

header("Cache-control: no-cache");
header("Expires: " . gmdate("D, d M Y H:i:s") . " GMT");

include($DOCUMENT_ROOT.'/include/user.php');

echo '
