Video

See a video demonstration of this topic here.

You can verify a page is being served from LSCache through the post-obit steps:

1. From a non-logged-in browser, navigate to your site, and open up the developer tools (usually, right-click > Audit). Open the Network tab.
2. Refresh the page.
3. Click the first resource. This should exist an HTML file. For example, if your page is http://example.com/webapp/, your first resource should either be something like example.com/webapp/ or webapp/.
4. You should see headings like to these:

                                       X-LiteSpeed-Cache: miss X-LiteSpeed-Cache-Control:public,max-age=1800 Ten-LiteSpeed-Tag:B1_F,B1_                                  

   These headings mean the page had not still been buried, only that LiteSpeed has now stored it, and it will exist served from cache with the side by side request.
5. Reload the page and you should see X-LiteSpeed-Enshroud: hitting in the response header. This means the page is beingness served by LSCache and is configured correctly.

   

Culling Headers

The X-LiteSpeed-Cache header is most mutual, but you may encounter X-LSADC-Cache if your site is served by LiteSpeed Web ADC. You may also see X-QC-Cache if your site was served via QUIC.cloud CDN. These alternate headers are also an indication that LSCache is working properly on your site.

Important

If you don't see Ten-LiteSpeed-Cache: hit or X-LiteSpeed-Cache: miss (or any of the alternative headers), then there is a problem with the LSCache configuration.

Non-Cacheable Pages¶

Sometimes there are pages which should not exist buried. To verify that such pages have indeed been excluded from caching, bank check the developer tools every bit described above.

You should run into headings similar to these:

                            10-LiteSpeed-Cache-Control:no-enshroud, esi=on X-LiteSpeed-Tag:B1_F,B1_                          

X-LiteSpeed-Cache-Control, when set to no-cache, indicates that LiteSpeed Server has served your page dynamically, and that it was intentionally non served from cache.

LSCache Cheque Tool¶

There'south a simple way to see if a URL is cached by LiteSpeed: the LSCache Check Tool.

Enter the URL you wish to check, and the tool volition respond with an easy-to-read Aye or No outcome, and a display of the URL's response headers, in case yous want to examine the results more closely.

In addition to LSCache support, the tool tin detect enshroud hits, and can detect when sites are using LiteSpeed Web ADC or QUIC.cloud CDN for caching.

Additionally, a Stale Cache Warning volition alert yous if browser enshroud is detected on dynamic pages. This is considering browser enshroud may interfere with the commitment of fresh content.
