Title: Problem with Cache plugin & REST API Last modified: July 20, 2023 --- # Problem with Cache plugin & REST API * Resolved [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/) * Hello. * Thanks for creating a great plugin… * I’m having a problem with the Cache Plugin, have been trying for hours but still don’t understand what’s going on. * I switch from **WP Rocket** to **Super Page Cache for Cloudflare Plugin**. * I use **rest_api** to update the “**View**” Meta for the post every time a User visits. The code is as follows: * ```wp-block-code function updatePostViewApi(WP_REST_Request $request) { $postID = $request['id']; $postType = get_post_type($postID); if (is_null($postType)) { return new WP_REST_Response(null, 404); } setPostView($postID, $postType); return new WP_REST_Response(null, 200); } add_action('rest_api_init', function () { register_rest_route('catalog', '/post_view_data1/(?P\d+)', array( 'methods' => 'GET', 'callback'=> 'updatePostViewApi', 'args' => array( 'id' => array( 'validate_callback' => function ($param, $request, $key) { return is_numeric($param); }, ), ), )); register_rest_route('catalog', '/post_view_data2/(?P\d+)', array( 'methods' => 'GET', 'callback' => 'updatePostViewApi', 'args' => array( 'id' => array( 'validate_callback' => function ($param, $request, $key) { return is_numeric($param); }, ), ), )); register_rest_route('catalog', '/post_view_data3/(?P\d+)', array( 'methods' => 'GET', 'callback' => 'updatePostViewApi', 'args' => array( 'id' => array( 'validate_callback' => function ($param, $request, $key) { return is_numeric($param); }, ), ), )); }); ``` * Then I use extra code to generate Shortcode and use Plugin: **Content No Cache** to load Meta via **Ajax **it works perfectly with **WP Rocket**. * However with the** Super Page Cache for Cloudflare Plugin**. Code only updates 1 time if CACHE Status is not **HIT**. * Looks like **Cloudflare **is caching rest_api and preventing it from working once Cache Status is **HIT**. Or am I missing an installation? * Thanks if you have any advice on how to fix this problem.

If you would like not to cache the REST API GET requests, you can enable this option inside the plugin settings: [https://i.imgur.com/WED1Wgk.jpeg](https://i.imgur.com/WED1Wgk.jpeg) This will ensure `/wp-json/` requests are not cached. 2. When Cloudflare caches a webpage HTML at the CDN level, the request never goes to your origin server, instead when a request is intercepted by Cloudflare, it checks if the page content is cached, it served the page content from the CDN cache without ever needed to reach out to the origin server. So, considering how CDN level page cache works, you might need to modify your code. The best approach is the create the API endpoints in PHP and then in JS level fetch the data, send POST requests to your endpoint to update those data. So that the entire process will happen asynchronously and will not be hampered by cache. * Thread Starter [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16914158) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) * Thanks for the reply. * I have installed wp-json. But the API error only updates the data once. Despite the announcement “Post view updated successfully” is displayed. But the value will not be + added to the Meta “View” * [https://prnt.sc/l2ut_xkaqssv](https://prnt.sc/l2ut_xkaqssv) * Of course, when logged in, this function works normally. * **There is one more strange problem.** * I have created some CPTs with urls appended .html at the end. Although logged in, these posts are still saved in cloudflare, still valid HIT. * [https://prnt.sc/H3jEcS_y-kfe](https://prnt.sc/H3jEcS_y-kfe) * For normal pages without the .html value, Dynamic will be displayed. this parameter issue is not removed on login. * How to configure ignore it? * Thanks a lot! * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16917115) * Hi [@cuongpham259](https://wordpress.org/support/users/cuongpham259/), 1. Have you enabled the option to not cache the WP JSON endpoint? If you have enabled that then CF won’t be caching the Endpoint. 2. For the `.html` page I can see the plugin is setting the cache-control header as `nocache` but due to some of your Cloudflare settings/rules CF is still caching it. 3. Can you please share a screenshot of your Cloudflare account’s Page Rule section, Cache Rule Section, if you have any cache rule share detailed screenshot of those cache rule, screenshot of the workers section. 4. Also please share the screenshot of the Cloudflare Dashbord > Caching > Browser Cace TTL section – make sure it is set to Respect Existing Headers. * Thread Starter [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16917183) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) 1. Yes. I enabled wp-json settings, which is weird. [https://prnt.sc/24j3NoDhArvy](https://prnt.sc/24j3NoDhArvy) 2.

The Page rule is causing all the problems. Please disable or delete the page rule. * Then also delete all the cache rules that you have added and check this newly updated implementation guide and add just 1 Cache rule as mentioned here: [https://gist.github.com/isaumya/af10e4855ac83156cc210b7148135fa2](https://gist.github.com/isaumya/af10e4855ac83156cc210b7148135fa2) * This should resolve your issue. Try it and let me know. * Thread Starter [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16917254) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) * You are correct, it looks like the Everything Page Rules Cache is corrupting the .html cache. The site is now working as expected. * Thank you! * I have 1 question. Is it possible to combine **Super Page Cache caching for Cloudflare** and **WP Rocket**? * Currently the speed for **non-logged **in users is super **fast**. But for ** logged in** users it is quite **slow**. * I want to leverage **WP Rocket **storage for **logged **in users, **disable caching for non-logged in users in both plugins** to avoid conflicts. Website distributes cache from cloudflare CDN and static html file from WP Rocket to logged in users. * This is possible? * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16917265) * Hi [@cuongpham259](https://wordpress.org/support/users/cuongpham259/), Yes there is, for that you need to check this guide: [https://gist.github.com/isaumya/d5990b036e0ed2ac55631995f862f4b8](https://gist.github.com/isaumya/d5990b036e0ed2ac55631995f862f4b8) * So, basically you can only use WP Rocket for static file optimization and no caching feature. I personally prefer using Perfmatters over WP Rocket as it not a page cahcing plugin at the core and has no page caching feature. But if you would like to use WP Rocket, check the guide. * For logged-in users your origin server’s speed matters a lot. For logged-in users pages will never be cached as for them content needs to be generated dynamically based on many logics, so PHP needs to generate those pages – they can’t be served from cache. * Thread Starter [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16927225) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) * Sorry for the late reply, I saw the doctor for 2 days. * You are correct, the speed for the logged in person depends on the actual server. But WP Rocket has a function to create a cache for logged in users, I have used it in the past and it is quite good. * Currently, I know that Super Page Cache for Cloudflare only supports parallel use with WP Rocket by banning WP Rocket from using Cache to avoid conflicts. However I had a couple of ideas and tested it out. * After adding some customization. The good news is that Super Page Cache for Cloudflare can now be used with non-logged in users and HTML cache with logged in users via the WP Rocket plugin. This is just the initial result, more time is needed to monitor and evaluate the results. * As for the “wp-json” problem. Because I use Security Plugin change wp-json = api-json. So will get an error like the case I described. So is there a way to customize the output of the json?… Hope there is an easy way to do this. * Thank you for supporting! - This reply was modified 2 years, 10 months ago by [cuongpham259](https://wordpress.org/support/users/cuongpham259/). * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16927264) * > After adding some customization.

I mean if this works for you, please consider sharing a guide of what you have done so that it can also help others. Looking forward to seeing your feedback after you test this thoroughly. * > As for the “wp-json” problem. Because I use Security Plugin change wp-json > = api-json.

It either send headers asking Cloudflare to cache the GET requests or if you have enabled the option inside the plugin then it will not cache the wp-json endpoint. Beside that this plugin doesn’t do anything special with the rest API endpoints. * Thread Starter [cuongpham259](https://wordpress.org/support/users/cuongpham259/) * (@cuongpham259) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-cache-plugin-rest-api/#post-16927285) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/) * Okay, it’s pretty simple. If everything works as expected. I will share again with the community. Just need more time to know that there is no implicit conflict here. * As a temporary solution, I would reset the default wp-json.
