Me again.
At the moment, when I write or edit site_configs at the ssh console and want to test, I need to clear the APC cache on admin page after every change in the config file and then reload the makefulltextfeed.php-page.
So I wish to have an option on admin page to allow user to bypass cache
with Yes|No|AccessKeyOnly
and then have a new checkbox on create page: don't use cache for config
and the URL parameter &nocache
So I could test changes in the config by just pressing F5 or Ctrl-R in the browser window.
