Hi, You could do it with post, if you set the right headers in your script. http://nl2.php.net/manual/en/function.header.php "Text from php.net" PHP scripts often generate dynamic content that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with: <?php header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past ?> Note: You may find that your pages aren't cached even if you don't output all of the headers above. There are a number of options that users may be able to set for their browser that change its default caching behavior. By sending the headers above, you should override any settings that may otherwise cause the output of your script to be cached. Additionally, session_cache_limiter() and the session.cache_limiter configuration setting can be used to automatically generate the correct caching-related headers when sessions are being used. Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

That's because you use Forms. The Explorer is just telling you that he don't will submit the posted formvars again. Well the message is very selfexplaining, but probably not easy to understand for you because i suggest you don't speak english that well. If you can live with some security problems use method="GET" rather than method="POST" this will give you no errors in this case probably.
