Configuration

Complete the 4 Steps below to set up and use the WP Super Cache Plugin successfully.

Step 1: WP Super Cache - General Settings

On the WordPress Dashboard, click the Settings tab from the side navigation menu to the left and select WP Super Cache.

• 

Under the Easy tab from the navigation menu that stretches across the top of your screen, click the radio button for Caching On (Recommended) option and select the Update Status button.

• 

Step 2: Advance Cache Configuration

Select the Advanced tab and configure the options to fit your website best.

Ensure that the Cache Delivery Method section is set to Simple (Recommended).

• 

Miscellaneous

Under the Miscellaneous settings, make sure to put a checkmark to the following recommended categories:

• Enable caching for all visitors
• Disable caching for logged-in visitors
• Compress pages so they’re served more quickly to visitors
• Cache rebuild. Serve a supercache file to anonymous users while a new file is being generated
• 304 Browser caching. Improves site performance by checking if the page has changed since the browser last requested it
  

Advanced

On the Advanced section, make sure to put a checkmark to the following recommended categories:

• Enable dynamic caching
• Clear all cache files when a post or page is published or updated
• Extra homepage checks
• Only refresh the current page when comments are made
  

Expiry Time & Garbage Collection

Set up your timeout for your website cache by configuring Expiry Time & Garbage Collection settings. WP Super Cache plugin will store the cached version of a page for 30 minutes before generating a new copy.

You may safely double the number up to 3,600 seconds for standard websites, which is equivalent to one hour as long as the server won’t have to generate cached files so often.

• 

Accepted Filenames & Rejected URLs

Under the Accepted Filenames & Rejected URLs setting, you have the option to choose the types of pages you want to cache as a rule of thumb. Post and pages are safe to cache; apparently, high dynamic pages such as products and checkouts are better off not getting cached. Once you put a checkmark, then click the Save settings button.

• 

Step 3: Content Delivery Network (CDN) Configuration - (optional)

Select the CDN tab and put a checkmark for the Enable CDN Support box.

• In the box next to the Site URL section, enter your website URL
• In the box next to the Off-site URL section, make sure you include the edge Address prefixed(e.g., http:// or https://)
• Enter any additional delivery domains (such as a custom URL) in the box next to Additional CNAMES
• To save the settings, click the Save Changes button
  

Step 4: Delete WP Expired and Content Pages

Select the Contents tab and choose either Delete Expired or click the Delete Cache button below to ensure that the cached content and expired pages are cleared.
