Title: [Plugin: WP Super Cache] Multisite Behavior Last modified: August 19, 2016 --- # [Plugin: WP Super Cache] Multisite Behavior * [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/) * Hi, * We’re using WP Super Cache on a multisite system, and we’re wondering a couple of things: * 1) We need to give users a little control, but without exposing the settings to them. For example, if a user makes a CSS change, we need to give them the ability to refresh their cache. This could be done by activating the setting to empty the cache when a new post is published. But, since the cache is network- wide, I believe, this will reset everyone’s cache. Is there a way to set it so that one user publishing or editing a post will only reset the cache for that particular blog? * 2) To keep the cache refreshed periodically, is there anything wrong with setting a cron job (maybe every hour) that clears the cache entirely? * Thanks, * Mark Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922141) * You could write a plugin that finds their cached files and deletes them but unfortunately Supercache doesn’t do that yet. It’s all or nothing I’m afraid. * No, you can clear the cache with a cron job. Nothing wrong with that but it will cause a load spike when all those pages are regenerated. * Thread Starter [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922150) * Unfortunately, writing a plugin would be beyond the scope of what I’m able to do in this case. 😉 * Thread Starter [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922151) * Followup question: * If I activate the option to clear cache when a post or page is published, does this mean that the entire (network-wide) cache will be cleared when any user publishes something? * If so, is this a problem? * Thanks, * Mark * Thread Starter [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922187) * > Supercache doesn’t do that yet. It’s all or nothing I’m afraid. * Have you considered expanding the multisite capability, given the growing popularity of multisite? The ideal solution would be for each blog to be cached separately, as I believe Quick Cache does. It would be great to hide major configuration settings from sub-site owners, but at least give them the ability to enable or disable caching, and to clear their cache. * Right now in a multisite setting, if a sub-site user makes changes and needs to clear the cache so those changes are made public, he or she is dead in the water, right? * Just a suggestion. Thanks for listening. * Mark * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922193) * Oh yes, I’d love if it deleted the cache files for one blog at a time! I’m sure it’ll be added in a future version. Hopefully someone reading this will decide to add that feature to the plugin! (hint hint to anyone finding this page in the future!) * Thread Starter [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922198) * If I knew how, I would. 🙂 * Thread Starter [markb1439](https://wordpress.org/support/users/markb1439/) * (@markb1439) * [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922202) * BTW, this is becoming a must-have feature for us. We need a way that individual sub-sites can clear their caches. Otherwise we know we’re going to have support ticket after support ticket asking why changes aren’t reflected on the site after changing themes, for example. I just don’t think we can offer network-wide caching without providing a way for users to clear their cache. And it’s not a viable solution to have the entire network’s cache cleared when a particular thing happens on a sub-site. 🙁 * I noticed that the Quick Cache plugin seems to automatically clear a sub-site’s cache if the theme is changed on that site. I’m going to peruse the code for inspiration, but I’m not a developer…so I don’t think I have the ability to add that functionality (or anything like it) to WP Super Cache. * Mark Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘[Plugin: WP Super Cache] Multisite Behavior’ is closed to new replies. * ![](https://ps.w.org/wp-super-cache/assets/icon-256x256.png?rev=3506220) * [WP Super Cache](https://wordpress.org/plugins/wp-super-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-super-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-super-cache/) * [Active Topics](https://wordpress.org/support/plugin/wp-super-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-super-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-super-cache/reviews/) * 7 replies * 2 participants * Last reply from: [markb1439](https://wordpress.org/support/users/markb1439/) * Last activity: [15 years, 3 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-multisite-behavior/#post-1922202) * Status: not resolved
