From what I've found out about APC I really want to install it. However I don't know if I can. I host with Yahoo Small business and have no access to my .htaccess file and not sure about my php.ini either. Does APC get installed to concrete5 or to my hosts server? I've looked on here and not found anything solid on how to install APC. Can someone who has done so already give the rest of us a basic step-by-step on how to do it. I don't know how to figure out if yahoo uses Linux or windows server either. Help would be greatly appreciated.
