[TYPO3-dev] how to clear cache_core

[Franz Holzinger]

Hello,

during the extension development under TYPO3 6.0 I sometimes run into a 
PHP problem which I can solve, but a cache_core file still contains the 
bug. And unfortunately I have no rights on the file system to delete the 
cache_core files or to edit them manually.

It does not even help to clear everything in the Install Tool or to 
deinstall the extension. The cache_core files still remain unchainged.

Warning: 
require_once(/var/www/path/web/typo3conf/ext/myextension/ext_localconf.php): 
failed to open stream: No such file or directory in 
/var/www/path/web/typo3temp/Cache/Code/cache_core/ext_localconf_85960581373e077434b42e18e3c86c43deaeb4e4.php 
on line 2724 Fatal error: require_once(): Failed opening required ...


How can I clear the cache_core files when the TYPO3 Backend has gone?
