Invalidating or overwriting a cached object? #256

Closed alexkozler closed 3 years ago

alexkozler commented 3 years ago

Let me describe my ASP.NET WebAPI scenario:

  1. Alex sends a message to a group of people, including Bill
  2. Bill does an HTTP GET to /message/get to fetch this message. This request's response is cached.
  3. Alex edits the message he sent in step 1
  4. Sam issues a /message/get to fetch the same message

In step #4 would Sam get the old message or the edited message? How do you invalidate/replace what the cache contains so that subsequent users don't get an outdated copy of the message prior to it's cached response expiring?

Apologies, as this was somehow lost and did not see it until now.

This is a generic question best asked in the forums. This has nothing specific to CacheCow.

Having said that, I am happy to help you but you have given zero information on where this is being cached. Do you mean a Cache proxy? Then depends on the proxy - CacheCow only support cache for the HTTP Client.
