I am using onebox as standalone gem. In my use case I want to read from cache only. Is there an easy way to fetch urls from cache only without any network hit?

I am using Rails 5.1.

Thanks.

While the onebox gem has an internal cache, it’s best for the user of the library to handle what should be cached and for how long.
