We have a multisite install that has garbage collection occur every 60 minutes. This means that if a user updates a page, it may be up to 60 minutes until it is updated when garbage collection occurs. Our goal is to have all changes appear live on the site immediately since there is some time sensitive info being published.
If we enable "Clear all cache files when a post or page is published." then every time a site on the install modifies or updates an existing page or post, they are good to go, their new updated is available to visitors immediately.
The issue is that when any post or page is updated the cache is not only cleared on the blog making updates, but every blog on the install. This can mean that each site is having it's cache reset on a regular basis as various sites on the install modify their content, making caching less useful as it is constantly being reset for every site anytime one site makes an update.
We have tried installing in mu-plugin and plugin folder hoping the plugins folder might afford control on a per blog basis to no avail.
Anyone know if it's possible to have wp super cache only reset the cache on the specific blog that has updated its content and not every blog on the install when the content is updated? Thanks!
