The question could be broken down into two questions: 1) when will it take for an item to be considered stale? and 2) how much space has already been used on the file system for caching?
You set general parameters in various caching products in Plone about how long an item is to be considered fresh or stale. (In Enfold Server, the caching product used is one called Chasseur). You don’t need Enfold Proxy to do that. EP can intercept these caching messages from Plone and keep cached copies on its hard drive and serve these cached items to browsers without troubling Plone or Enfold Server. EP may still store the item in the cache – but it will immediately be considered stale. Thus, the next request for this item will cause EP to validate the item with the remote server – and if the item has not changed at the server, EP will use the cached copy instead of sending the request to Plone/Enfold Server. For the second example. suppose the default_age was 5 seconds. For the first 5 seconds after a request, EP would serve it directly from its cache. After 5 seconds, it remains in the cache, but is considered stale. The next request is as above – validated at the server. If the s
