For example:
1. Add a hidden field into the form named "typo3_user_int" and set it to 1
2. Change TS for your plugin to have this:
	plugin.tx_extkey_pi1 = USER
	[globaVar = GP:typo3_user_int=1]
	plugin.tx_extkey_pi1 = USER_INT
	[global]
    It will make your plugin non–cachable when form is submitted. The plugin will process data and execute.
3.  Clear cache for a page if it needs to show new data. PHP code:
	// Include file on global level
	require_once(PATH_t3lib . 'class.t3lib_tcemain.php');
	// Inside form processing:
	$tce = t3lib_div::makeInstance('t3lib_TCEmain');
	$tce->clear_cacheCmd($pageId);

Again, get the book on the extension programming. It will save lots of time and questions :)
