Issue/Introduction

This article explains how caching of HTTPS content on the ProxySG or Advanced Secure Gateway (ASG) works.

Resolution

To cache HTTPS content, you must enable SSL intercept. If the HTTP response from the OCS contains the headers no-store, no-cache, pragma : no-cache, you must configure one more rule in the Web Content layer to force cache it:

<Cache>
    cache(yes) force_cache(response-no-cache,response-no-store,private)   


To view the cached HTTPS content, type the following in the browser address bar:

https://<proxy_IP_address>:8082/CE/Info/https/<web_page>
where <web_page> is the web page for which you want to view cached content 


For example, if the web page is:
https://www.youtube.com/watch?v=Puuhx8QvJNU

Type the following:
https://<proxy_IP_address>:8082/CE/Info/https/www.youtube.com/watch?v=Puuhx8QvJNU

To delete this, type:
https://proxy_IP:8082/CE/Delete/https/www.youtube.com/watch?v=Puuhx8QvJNU
