 * Hello,
 * We recently updated Litespeed cache and we got this message from Google Search
   Console:
    (we are also using a LiteSpeed server).
 * We manage other sites, but this is the only site that we manage that uses a Litespeed
   server with a Litespeed cache, and since this just came up after the most recent
   update we wanted to find out if this is related before we go on a hunt to try
   figure this out.
 * Google Search Console:
    New requirements for SharedArrayBuffers Google systems
   have recently detected that SharedArrayBuffers (SABs) are used on your website,
   but COOP and/or COEP headers are not served.
 * For Web Compatibility reasons Chrome is planning to require COOP/COEP for the
   use of SABs from Chrome 91 (2021-05-25) onwards. Please implement ‘cross-origin-
   isolated’ behavior on your site.
 * Our Litespeed report number:
    QULHAUGY
 * Best regards,

 * Hi,
 * [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer)
 * it looks like something to do with JS
 * and as of version 3.6.3 , I don’t find this keyword in our source code , it must
   be coming from your other plugin/theme
 * please try do a text search for this keyword

    Hi, can you be more specific
   to which keyword you are suggesting? We have done several searches and found 
   nothing yet.

 * Hi [@qtwrk](https://wordpress.org/support/users/qtwrk/)
 * It seems that SharedArrayBuffer is used by React, which is used by Gutenberg,
   and probably other things.
 * React has an outstanding issue for this:
 * [https://github.com/facebook/react/issues/20829](https://github.com/facebook/react/issues/20829)
 * On our site we could not pinpoint the direct source of the SharedArrayBuffer.
 * After doing some reading on the subject my understanding is that this can be 
   mitigated if we add to the site header the following:
 * Cross-Origin-Embedder-Policy: require-corp
    Cross-Origin-Opener-Policy: same-
   origin
 * And we though about implementing this using. htaccess rule like this:
 *     ```
       # Cross-Origin-Embedder-Policy: require-corp
       <IfModule mod_headers.c>
         Header set Cross-Origin-Embedder-Policy: "require-corp"
       </IfModule>
   
       # Cross-Origin-Opener-Policy: same-origin
       <IfModule mod_headers.c>
           Header set Cross-Origin-Opener-Policy: "same-origin"
       </IfModule>
       ```
   
 * Does implementing this affects in anyway the way Litespeed works?
