I already have a CDN. Can I still use AppTrana?

Yes, while onboarding we ask if you already have CDN. If you are already using any other CDN, let us know and we will configure your site to enable only protection. At any point in future, you would like to switch to our CDN. Please reach out to our support and they will help you out.

Is dynamic content caching possible?

In general, you should not cache Dynamic pages. However, we may identify, or extract, some of the static content out of these dynamic pages and cache it on the CDN. This might be applicable to certain product display pages where the main URL remains the same but query parameters changes. Based on different query string parameter values, the content of the page changes. So, you can cache these pages for some amount of time and improve the page load time for the end users by caching it at the CDN server, and reducing load on your origin server. This will improve end user’s experience.

You can enable such configuration by contacting Indusface Support.

Will CDN work for HTTPS traffic?

Yes, AppTrana works for HTTPS traffic and the SSL used for WAF in AppTrana will be used by CDN to serve HTTPS traffic.
