Dear all,
I use php to write update webpage, Although the data has already been updated, the new data has not appeared some times until we refresh the webpage. This may be due to the proxy or the temporary internet files in the windows folder. Anyway, I has added the following code to the beginning of the webpage.
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
but no vain.
Anyway, please to give effective method to make sure the updated webpage can be appeared without any refresh or delay.
Simon
