Questiion. Does expriry option gets reset when cache is served to the user?

In the expire option, you can specify a time frame to delete a cache entry. I assume that time starts from when the cache entry is created but does it get reset when the request is served from the cache?

Ex
1st request -> cache created -> expires after 60 sec

After 30 sec
2nd request -> cache already there -> served from cache -> what would be the remaining time for the cache to expire

30 sec or 60 sec?

it would be 30 seconds as I hope you expect, if you want your cache to last longer, simply set the expiration to a longer value.
If a page is requested every 30 seconds for a page that expire after 60 seconds and that library will change the expiration cache to 60 seconds after every request you will end up with a page that never renew.

Although there's an interesting thought here, there could be an option to set the cache in redis for ever along with the expiration time, when the expiration time is expired, the library could return the cache one last time and rebuild the cache in the background for the next requests.
Although it would not be a good idea to make that the default behavior, it could be an opt-in option. Similar to an http cache control stale-while-revalidate.
