What is local caching of data?
How does local caching reduce network traffic?
- Local caching reduces network traffic because the data is written once. Such caching improves the apparent response time of applications because the applications do not wait for the data to be sent across the network to the server. Local caching of data to be read can appear to speed things up by means of reading ahead.
What is web caching and how does it work?
- Web caches reduce latency and network traffic and thus lessen the time needed to display a representation of a resource. By making use of HTTP caching, Web sites become more responsive.
What are the different types of caching?
- 1 Different kinds of caches. Caching is a technique that stores a copy of a given resource and serves it back when requested. ... 2 Targets of caching operations. HTTP caching is optional but usually desirable. ... 3 Controlling caching. ... 4 Freshness. ... 5 Cache validation. ... 6 Varying responses. ... 7 See also. ...

Local caching of data is a technique used to speed network access to data files. It involves caching data on clients rather than on servers when possible. The effect of local caching is that it allows multiple write operations on the same region of a file to be combined into one write operation across the network.

Using a shared cache can help alleviate concerns that data might differ in each cache, which can occur with in-memory caching. Shared caching ensures that different application instances see the same view of cached data. It does this by locating the cache in a separate location, typically hosted as part of a separate service, as shown in Figure 2.
