Does NFS client cache?
To improve performance, NFS clients cache file attributes. Every few seconds, an NFS client checks the server’s version of each file’s attributes for updates. Changes that occur on the server in those small intervals remain undetected until the client checks the server again.
Is cache server side or client side?
Is it client side or server side? It can be either, or both. Server side caches are generally used to avoid making expensive database operations repeatedly to serve up the same content to lots of different clients. Client side caches are used to avoid transferring the same data over the network repeatedly.
What is client side caching?
Client-side caching duplicates the data of previously requested files directly within browser applications or other clients (such as intermediate network caches). Client cache is the most efficient type of caching, because it allows browsers to access files without communicating with the web server.
How does server side cache work?
Server side web caching typically involves utilizing a web proxy which retains web responses from the web servers it sits in front of, effectively reducing their load and latency. Client side web caching can include browser based caching which retains a cached version of the previously visited web content.

How to disable cache on Windows Server 2012 NFS?

What does lookupcache = None Mean in NFS?
lookupcache=none. If the client ignores its cache and validates every application lookup request with the server, that client can immediately detect when a new directory entry has been either created or removed by another client. You can specify this behavior using lookupcache=none.
How to clear browser’s cache from server side?
I need to immediately clear the browser’s cache after user logs out since cached data would be vulnerable. Client’s browser should be enforced to clear the Cache from server side. Also all cache policies must be exposed to the client from the server side. Is there any solution to this problem?
