How to cache a page in Bitrix?

Question

1C-Bitrix

Tell me, is there an opportunity in Bitrix to cache pages completely so that when MySQL crashes, the site still works?
Now on the site, requests to the database are not only through the components that are cached, but also directly in the files.
Redis is connected for caching.

IMHO: look at the composite cache. But it still makes ajax requests to dynamic areas, and I don’t know how it will work in case of a database crash.
Perhaps it will be easier to put HAProxy on the front and configure it.
