Configuring the UltraStack cache includes many options that are normally considered advanced. The advanced options for the cache are accessed through a link at the bottom of the Cache Manager page. The options available with the advanced section let you fine-tune how NGINX caching works. Follow the steps below to learn about these options and how to use them.

How to Access the Cache Manager Advanced Options
- Login to the cPanel
- Scroll down to the Software section.
- Click on Cache Manager.
- In the Cache Manager, scroll to the bottom of the screen. Click on the link labeled Show Advanced Options.
Description of the Advanced Options
- Proxy Protocol – use HTTP or HTTPS; only use when an SSL certificate is installed.
- ModSecurity Response Cache time – Cache refresh time for requests stopped by ModSecurity 406 error
- 404 Error Cache Time – Cache refresh time for hits that return 404 error
- Bypass Cookie – This is a list of strings that can be used to trigger a bypass of the cache. This normally used with WordPress pages that should not be cached. This may also apply to plugins or a non-WordPress CMS
- Max Requests Per Minute – Set the number of requests per minute allowed to access rate-limited URLs; setting the option to zero will disable it
- Enable Gzip Compression – Compress response via gzip; this will set the gzip compression to the selected level
- Accelerate static content – This allows the NGINX Cache to bypass the Apache webserver directly in order to serve static content; Disable for WordPress multi-site or another application with dynamic routing
- Static Content Path – List URLs that should be served directly by NGINX; add paths by clicking on the “+” sign
- Force Passthru Path – List URLs that should always be forwarded to Apache; add paths by clicking on the “+” sign
- Error page – Specify a customer user-created page to display if the server encounters a 503 (service unavailable) or 504 (gateway timeout) error
