There is no explicit mechanism for disk based caching. If you are writing a plugin or theme you intend to distribute you should be careful with allocating a folder for it, probably better to have some kind of an option for a user to configure that location. If this is something for a specific site, … Read more
In reality it is very hard to know when a page is affected by an edit. A page contains footer, memus, widgets, shorcodes and meta data which might change “globaly”. Having a general detection which page is affected by any such change is bordering the impossible. Cache expiration in general is just a very hard … Read more
Typically page builder themes and plugins are compatible with caching. The reason they still tend to slow down websites is because they are very resource-intensive. In WP there are two main resources – data from the database, and files. Because page builders can do almost anything you can imagine, they have to come with enough … Read more
Do these lines mean HTTPS urls will not be cached?

The problem is that I used the wrong type of quote marks. You cannot see it in my first post because apparently they were changed when I pasted in the code.

W3 Total Cache (which I currently use) can do that … Read more
Cache duration value (defaults to 43200 seconds) is set when feed object is generated and passed through wp_feed_cache_transient_lifetime filter with additional argument being feed URL. This allows to conveniently filter it both globally and for specific feeds. See fetch_feed() source for this and other hooks you can use to modify its behavior.
