LSCWP Resources

第三方兼容性

The vast majority of plugins and themes are compatible with LSCache. Our API is available for those that are not. Use the API to customize smart purging, customize cache rules, create cache varies, and make WP nonce cacheable, among other things.

隐私

这个插件包括一些建议的文本,你可以通过 WordPress 隐私设置中的指南添加到你网站的隐私政策中。

For your own information: LiteSpeed Cache for WordPress potentially stores a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

除了缓存,我们的 WordPress 插件还有 QUIC.cloud 提供的在线功能,用于图像优化、CSS 优化和低质量图像占位符服务。当这些优化功能之一被请求时,数据被传输到一个远程的 QUIC.cloud 服务器,进行处理,然后传输回来在你的网站上使用。现在,如果使用 QUIC.cloud CDN,它使用 LSCache 技术访问您的网站,然后将您的网站托管给全球的其他人,而且您的数据不会以任何方式传输给或被 QUIC.cloud 员工访问,除非在提供维护或技术支持时有必要。QUIC.cloud 将该数据的副本保留 7 天,然后永久删除。同样,WordPress 插件有一个报告功能,网站所有者可以将环境报告传输给 LiteSpeed,以便我们可以更好地提供技术支持。这些功能都不会收集任何访客数据。只涉及服务器和网站数据。

Please see the QUIC.cloud Privacy Policy for our complete Privacy/GDPR statement.

Why do the cache features require LiteSpeed Server?

Answer:

This plugin communicates with your LiteSpeed Web Server and its built-in page cache (LSCache) to deliver superior performance to your WordPress site. The plugin’s cache features indicate to the server that a page is cacheable and for how long, or they invalidate particular cached pages using tags.

LSCache is a server-level cache, so it’s faster than PHP-level caches. Compare with other PHP-based caches.

A page cache allows the server to bypass PHP and database queries altogether. LSCache, in particular, because of its close relationship with the server, can remember things about the cache entries that other plugins cannot, and it can analyze dependencies. It can utilize tags to manage the smart purging of the cache, and it can use vary cookies to serve multiple versions of cached content based on things like mobile vs. desktop, geographic location, and currencies. See our Caching 101 blog series.

If all of that sounds complicated, no need to worry. LSCWP works right out of the box with default settings that are appropriate for most sites. See the Beginner’s Guide.

Don’t have a LiteSpeed server? Try our QUIC.cloud CDN service. It allows sites on any server (NGINX and Apache included) to experience the power of LiteSpeed caching! Click here to learn more or to give QUIC.cloud a try.

What about the optimization features of LSCache?

Answer:

LSCWP includes additional optimization features, such as Database Optimization, Minification and Combination of CSS and JS files, HTTP/2 Push, CDN Support, Browser Cache, Object Cache, Lazy Load for Images, and Image Optimization! These features do not require the use of a LiteSpeed web server.

Is the LiteSpeed Cache Plugin for WordPress free?

Answer:

Yes, LSCWP will always be free and open source. That said, a LiteSpeed server is required for the cache features, and there are fees associated with some LiteSpeed server editions. Some of the premium online services provided through QUIC.cloud (CDN Service, Image Optimization, Critical CSS, Low-Quality Image Placeholder, etc.) require payment at certain usage levels. You can learn more about what these services cost, and what levels of service are free, on your QUIC.cloud dashboard.

What server software is required for this plugin?

Answer:

A LiteSpeed solution is required in order to use the LiteSpeed Exclusive features of this plugin. Any one of the following will work:

  1. LiteSpeed Web Server Enterprise with LSCache Module (v5.0.10+)
  2. OpenLiteSpeed (v1.4.17+)
  3. LiteSpeed WebADC (v2.0+)
  4. QUIC.cloud CDN

The General Features may be used with any web server. LiteSpeed is not required.

Does this plugin work in a clustered environment?

Answer:

The cache entries are stored at the LiteSpeed server level. The simplest solution is to use LiteSpeed WebADC, as the cache entries will be stored at that level.

If using another load balancer, the cache entries will only be stored at the backend nodes, not at the load balancer.

The purges will also not be synchronized across the nodes, so this is not recommended.

If a customized solution is required, please contact LiteSpeed Technologies at info@litespeedtech.com

NOTICE: The rewrite rules created by this plugin must be copied to the Load Balancer.

Where are the cached files stored?

Answer:

The actual cached pages are stored and managed by LiteSpeed Servers.

Nothing is stored within the WordPress file structure.

Does LiteSpeed Cache for WordPress work with OpenLiteSpeed?

Answer:

Yes it can work well with OpenLiteSpeed, although some features may not be supported. See Plugin Features above for details. Any setting changes that require modifying the .htaccess file will require a server restart.

Is WooCommerce supported?

Answer:

In short, yes. However, for some WooCommerce themes, the cart may not be updated correctly. Please visit our blog for a quick tutorial on how to detect this problem and fix it if necessary.

Are my images optimized?

Answer:

Images are not optimized automatically unless you set LiteSpeed Cache > Image Optimization > Image Optimization Settings > Auto Request Cron to ON. You may also optimize your images manually. Learn more.

How do I make a WP nonce cacheable in my third-party plugin?

Answer:

Our API includes a function that uses ESI to “punch a hole” in a cached page for a nonce. This allows the nonce to be cached separately, regardless of the TTL of the page it is on. Learn more in the API documentation. We also welcome contributions to our predefined list of known third party plugin nonces that users can optionally include via the plugin’s ESI settings.

How do I enable the crawler?

Answer:

The crawler is disabled by default, and must be enabled by the server admin first.

Once the crawler is enabled on the server side, navigate to LiteSpeed Cache > Crawler > General Settings and set Crawler to ON.

For more detailed information about crawler setup, please see the Crawler documentation.

What are the known compatible plugins and themes?

Answer:

The vast majority of plugins and themes are compatible with LiteSpeed Cache. The most up-to-date compatibility information can be found in our documentation
