As a senior website operations expert, I am well aware of how important it is to balance the real-time nature and high performance of website content.In AnQiCMS (AnQiCMS) such an efficient content management system, we fully utilize its powerful template functions and caching mechanism to optimize the website's access experience.bannerListWill the label's data be cached? And how can we effectively clear these caches when we need to update the Banner?

Understand the caching mechanism of Anqi CMS in depth

AnQi CMS, as an enterprise-level content management system developed based on the Go language, one of its core advantages is high performance and high concurrency.To achieve this goal, the cache mechanism plays a crucial role.In short, cache is like a high-speed temporary storage area that saves copies of frequently accessed data or page content, so that the system can directly obtain it from the cache when the user requests it again, without the need to repeatedly execute complex database queries and template rendering processes.This greatly reduced the server load, significantly improving the website's response speed and user experience.

In Anqi CMS, this caching mechanism is multi-level, covering data query results, template compilation files, and even some static pages. For the content displayed on our front-end, especially through template tags (such asbannerList)Data dynamically fetched and rendered, the system usually caches it.

Then, specificallybannerListThe label, its data will be cached.This means that after you perform operations such as uploading images, adjusting the order, modifying links, or even deleting in the 'Content Management' or 'Page Resources' section of the AnQi CMS backend management interface, the front-end page will not immediately display these latest changes.

This is because when a user first visits a page containing a Banner, the Anqi CMS reads the Banner data from the database, then combines it with template files to render the data into HTML code, and stores the rendered result (or at least the data itself and the intermediate products required for rendering) in the cache.After other users, and even yourself, visit this page again, the system will prioritize retrieving this old rendering result from the cache instead of re-executing the time-consuming query and rendering.

This mechanism is generally beneficial because it ensures the quick loading of the website.When content is updated, especially when important visual elements like a Banner need to take effect immediately, this cache becomes a 'barrier'.

How to efficiently clear Banner cache

When you find that the background has updated the Banner, but the front-end page still remains indifferent, you need to manually intervene, clear the system cache of Anqi CMS.AnQi CMS provides a concise and clear cache cleaning function to ensure that your website content is updated in a timely manner.

The operation process of clearing Banner cache is usually as follows:

First, you need to log in to the Anqi CMS backend management system.In the left menu or top category in the background, find the options related to "System SettingsThere will usually be an entry named "Update Cache" or "System Cache" under these categories.

Click to enter the "Update Cache" page, where the system will provide a clear button or option to prompt you to perform cache cleanup.Click the button after confirming that everything is correct.The AnQi CMS will perform a series of cleaning tasks, including deleting old template compilation files, clearing various data caches, etc.This process is usually completed quickly.

Once the cache is cleared, you can refresh the website's front page.At this time, the system will be forced to reload the latest Banner information from the database because it cannot find the old cached data, and then re-render it to ensure that your latest Banner content is displayed correctly.

The importance of cache management and **practice

Learn to clear the cache is just the first step, what's more important is to understand the status of cache management in website operation.The cache design of AnQi CMS is for performance improvement, therefore, we do not recommend clearing the entire system cache frequently unless necessary.Frequent cache clearing means that every visit requires the page to be regenerated, which increases the server load and temporarily reduces website performance.

**Practice is:

  • Regularly update with a plan:When you have important content updates (such as banners, activity pages, article releases, etc.) that need to take effect immediately, then perform cache clearing.
  • Phased testing:If it is a major overhaul or feature launch, you can clear the cache and verify in the test environment first, and then apply it to the production environment.
  • Understand the scope of impact:The 'Update Cache' feature of Anqi CMS is usually a site-wide cache cleaning.This means it will not only affect the Banner, but also all other cached pages and data.Therefore, when performing this operation, please ensure you understand the potential impact.
  • Independent management of multiple sites:If you use the multi-site management function of Anqi CMS and each site has an independent cache storage path (for example, in Docker deployment, each site's cache directory is independent), then clearing the cache of one site will not affect the cache data of other sites, which provides you with a finer control granularity.

Understanding the cache mechanism of AnQi CMS and being proficient in using the "Update Cache" feature allows you to maintain high website performance while flexibly controlling real-time content updates, ensuring that your website always presents the latest and most attractive content.

Frequently Asked Questions (FAQ)

Q1: Why did the Banner still show the old content on the front page after I updated it on the background?

A2: The main purpose of clearing the cache is to force the system to regenerate the page content to display the latest data.Within a short period of time, during the first visit after the cache is cleared, the website's loading speed may slightly decrease because the system needs to re-query the database, compile templates, and generate new cache.This is usually temporary, once the new cache is generated, the website performance will return to normal, and even better user experience may be brought by loading the latest data.
