How do you do a front end cache?
Based off the content characteristic of each resource you can now create an optimal caching strategy.
- If the content is immutable then cache it for as long as possible. For example: Cache-Control = max-age: 31536000 .
- If the content is mutable then we would like browsers to cache the file until we change it.
What is front end cache?
Frontend caching is a largely underused technique, yet it can be a very powerful optimisation if used correctly. A good reason for caching data in the browser is because we can safely assume that a network request is more expensive and unpredictable than retrieving data from a local cache.

What to expect from a cached request header?
By sending the “If-None-Match” request header with the ETag of a cached resource, the browser expects either a 200 OK response with a new resource, or an empty 304 Not Modified response, which indicates that you should use a cached resource instead of downloading a new one.

Why do I need no cache header in Netscape?
Including the Pragma: no-cache header is a precaution that protects legacy servers that don’t support newer cache control mechanisms and could cache what you don’t intend to be cached. Some would argue that unless you have to support Internet Explorer 5 or Netscape, you don’t need Prama or Expires.
How are headers used to manipulate cache behavior?
There are multiple headers available that developers and ops people can use to manipulate cache behavior. The old spec is mixing with the new: there are numerous settings to configure, and you can find multiple users reporting inconsistent behavior.
