What types of data does the 'Update Cache' feature on AnQiCMS backend mainly clean up?

As an experienced website operations expert, I am well aware of the importance of 'caching' for website performance and data real-time accuracy.In the daily operation of AnQiCMS (AnQi CMS), the "Update Cache" function seems simple, but it actually plays a core role, ensuring the timely update of our website content and smooth operation of the system.What exactly does this function mainly clean up?Next, I will explain it to you in detail.

In simple terms, the 'Update Cache' feature of AnQiCMS backend is designed to clear various data copies temporarily stored by the system to improve access speed and reduce database load.These data copies may cover the front-end display content of the website, background configuration information, and even the underlying database query results.Promptly clear these caches to ensure that users access the latest and most accurate website information.

Firstly, the most direct impact is evident inPage rendering cacheTop.AnQiCMS to quickly respond to user requests, it will temporarily store the front-end page content after template parsing and data filling.This includes the article list, article detail page, single page, category page, navigation menu, and even some blocks (such as the latest news, hot products) of the final rendering results of dynamic content.If you publish a new article, modify existing content, adjust the classification structure, or update the navigation menu, if you do not clean up this part of the cache, users visiting are likely to still see the old version of the content.Therefore, clearing the page rendering cache can force the system to regenerate these pages, ensuring that the front-end display is consistent with the background data.

Secondly, AnQiCMS background featuresSystem configuration and data cachingIt is also the focus of cleaning the "update cache" feature.We know that AnQiCMS provides a wealth of configuration options, such as website name, URL structure (pseudo-static rules), contact information, SEO meta information (TDK), language packages, and user group permissions, etc.This configuration information will be loaded and cached after the system starts or is modified to avoid reading the configuration file or database each time a request is made.When you adjust these global settings in the background, such as changing the website name, replacing the Logo, updating the pseudo-static rules, or adjusting the contact phone number and email, you need to go through "Update Cache" to make these new configurations take effect immediately.Otherwise, the website may still run with the old configuration, leading to discrepancies in front-end display or back-end logic.

Furthermore, to further improve data read efficiency, AnQiCMS will also optimize someFrequent access to database query resultscache.This may include the content model definition of the website, the category tree structure, the tag list, and even some statistical data.For example, when you customize the content model by adding, deleting, or modifying fields, or when you adjust the structural classification of articles, these changes may affect how the system understands and processes content.Clearing this part of the cache will prompt AnQiCMS to reload the latest data structure and query results, ensuring that all operations dependent on these underlying data can proceed normally.

In short, the 'Update Cache' feature is like a comprehensive 'refresh' for AnQiCMS, cleaning out those temporarily stored data for efficiency that may be outdated.The purpose is to allow the website to reflect any updates and adjustments we make on the backend in a timely and accurate manner.Master and make good use of this feature, it is the key for every AnQiCMS operator to ensure the healthy and efficient operation of the website.

Frequently Asked Questions (FAQ)

Q1: Why didn't the front page update immediately after I modified the content of an article? A1: This is likely because your website is still displaying old page cache.AnQiCMS to improve access speed, will cache the generated page content.After you modify the article, you need to go to the AnQiCMS background, find and click the "Update Cache" function, and clear this part of the cache.This system will regenerate and display the latest modified article content you have made.

Q2: Will clearing the cache cause loss of website data? Is this operation safe? A2: You can rest assured that clearing the "Update Cache" feature in the AnQiCMS backend is completely safe, and it will not cause any data loss on your website.This feature simply deletes the temporary data copies stored by the system to enhance performance, such as page rendering results, configuration information cache, etc., while the original data you create in the background, such as articles, images, and configurations, are stored in the database and will not be affected.

Q3: What is the difference between the "Update cache" on the back end and clearing the cache in our browser? A3: These two are different. The 'Update Cache' in AnQiCMS backend is for cleaning the server-side (backend) cache to ensure that the server provides the latest data to users.And the cache you clear in your browser (such as history, Cookies, website data, etc.) is a client-side (front-end) cache, which clears the website resources stored on your local computer to speed up loading speed.Sometimes, even if you have cleared the server-side cache, the user's browser may still be displaying the old local cache. In this case, you also need the user to manually clear the browser cache or force refresh (Ctrl+F5/Cmd+Shift+R) to see the latest content.
