Sitecore CMS : Client Browser cache Nightmare

If there is a system with CMS and CMS supplies data to non CMS system very frequent changes then one has to keep in mind about the browser cache.

There can be a scenario , your application is hosted in self kiosk mode where it has to get refresh after every 2 mins to reflect right data and don't go into sleep mode. Either you enabled attract screen or get the fresh data from the server to keep it going.

Now imagine a situation where content author has published some content and your browser refresh after 2 mins and content is not changes. BOOO......!

What if, it is browser cache is not clear and we are using angularjs to give the best user experience.

Here is the brute force method of disabling browser client side caching mechanism. This will reduce the efficiency and response time of application before you apply this.

Mixed Content Error http vs https


 Problem:

Mixed Content: The page at 'https://sitename.com/abc/def' was loaded over HTTPS, but requested an insecure script 'http://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places&sensor=false'. This request has been blocked; the content must be served over HTTPS

Solution:
The browser will load with the correct protocol. This goes for images as well. Then if the user comes from http, it will load http, https if https.

 How to Fix the Problem

If the problem appears on regular HTTPS secured pages with content that is being loaded via the insecure HTTP protocol, you can control how the content behaves.
Links with “http://” extensions need to change to contain the “s” part of HTTP protocol (https://) pointing out to an SSL-reserved port. A more elegant way of handling different protocols is to have only slashes where port is expected “//”. so that page can use the protocol used to open the page itself:
