my code only works when i keep reloading

[jasonchan]

Hi all,

I want to immplement a stemming algorithm for my project. So i installed the
stem-php which i got from here
http://www.tutorbuddy.com/software/versions.php/stem-php.

However the extension works in very low probability, what i means is that
the code
always not works, but would works in one or two times.

I write a code and run in broswer, it usually not works in the first try,
but if i keep pressing "reload", it would work for sometime.

So what is the problem?

A possibility is, that the results of the scripts are cached anywhere (browser or proxy).

To deactivate any proxy-cache, code this four header instructions at the very beginning of every script:

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // some gone date 
header ("Last-Modified: " . gmdate ("D, d M Y H:i:s") . " GMT");
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 
header ("Pragma: no-cache"); // HTTP/1.0 

To deactivate browser cache insert following meta tag to your html codes

 
<META http-equiv="expires" content="0"> 

At first close all your browser windows, delete all temporary stored internet files from your computer and try again.
