That's the point.
For developing i deactivate config cache:
$TYPO3_CONF_VARS['EXT']['extCache'] = '0';
normally also
$TYPO3_CONF_VARS['SYS']['displayErrors'] = '1';
$TYPO3_CONF_VARS['SYS']['sqlDebug'] = '1';

For FE i clear both, page and page_section (all) and BrowserCache (Strg+F5)

On productive sites there is important not to clear all the cache because of 
performance reasons.
