WordPress likes to redirect dead links to a nice page with your theme and widgets are loaded. What effect does this have on cpu load if bots are hitting thousands of dead links due to moving a folder?
I installed Redirection plug in and it logged tens of thousands of dead links. Obviously you can't control who tries to access your missing content so is there a way to force the site to not render the WP page if it is being accessed by a crawler? Maybe something in .htaccess?
