-Chromium, and hence the Chrome and Edge browsers, are very sensitive to certificate problems when determining if an item should be cached. Specifically, if a request is done dynamically (type: xhr) and the server is using a self-signed certificate, then the browser will not send the `if-none-match` header. [Reference]( https://issues.chromium.org/issues/40666473). If self-signed certificates are required during development in lower environment, then use FireFox to test the caching behavior.

+## Verifying behavior
+
+The behavior of Delta can be verified as follows:
+
+ * Open a page in the site
+ * Open the browser developer tools
+ * Change to the Network tab
+ * Refresh the page.

+Cached responses will show as 304 in the `Status`:

+### Ensure cache is not disabled
+
+If disable cache is checked, the browser will not send the `if-none-match` header. This will effectively cause a cache miss server side, and the full server pipeline will execute.

 ## Programmatic client usage
 
 Delta is primarily designed to support web browsers as a client. All web browsers have the necessary 304 and caching functionally required.
