About browser cache
If content is cached on the browser the first time that it is loaded, the browser does not have to request that content again. This helps to improve performance as well as the network load.
When a browser sends a request to the mid tier server, the response might contain a Cache-Control header. The browser uses this Cache-Control header to identify whether the content should be cached and when this cached content expires. The browser uses the cached content until it expires, after which it sends a new request to the mid tier server. If the response does not contain the Cache-Control header, the browser sends a new request each time.
After browser cache is enabled, if the content on the mid tier server changes, the browser does not detect the change because it uses the content from its cache.
