• Runtime Caching refers to adding a response to a cache as you go.

Artificially speed up the internet connection with pre-caching, web pages are cached (momentarily saved) so that they load promptly the next time you visit that page.

• Use a service worker to cache resources on the customer's device because accessing cache memories is more immediate than accessing the main memory.
• Prefetching allows applications to maximize performance and minimize wait times by preloading resources that customers will need before they request them.

Allows to put restrictions on a cache and define how long it should allow details to be stored in a cache or how many items should be stored in a cache.

• Restrict the number of cache entries.
• Restrict the time range of cached entries.
• Helps to remove old entries for the new response.

Cache strategies improve the responsiveness of the website. Caching allows content to be regained faster because an entire network request execution is not necessary. Drafting used cache strategies name below:

• Cache First - To fulfill the request using the cached response without using the network.
• Network First - Network First strategy is an essential solution for requests that are performed repeatedly.
• Network Only - To fulfill the specific request from the network.
• Cache Only - To assures that responses are received from a cache.

Performed search request fails instantly due to the dropped internet connection or server down problem. So the implemented BackgroundSync is an absolute solution to this problem.

• BackgroudSync for the search page is implemented.
• Let the service worker detect the failed network request and register to receive a sync event for delivering the requested search result when connectivity has returned.
• Sync events automatically replay failed requests even if the customer has left the app to deliver the requested search result.
