 In Node.js, the answer involves a WebSocket to TCP socket proxy, [Asyncify](https://emscripten.org/docs/porting/asyncify.html), and patching deep PHP internals like php_select. It's complex, but there's a reward. The Node.js-targeted PHP build can request web APIs, install composer packages, and even connect to a MySQL server.
 
-In the browser, networking is supported to a limited extent. Network calls initiated using `wp_safe_remote_get`, like the ones in the plugin directory or the font library, are translated into `fetch()` calls and succeed if the remote server sends the correct CORS headers. However, a full support for arbitrary HTTPS connection involves opening a raw TCP socket which is not possible in the browser. There is an [open GitHub issue](https://github.com/WordPress/wordpress-playground/issues/85) that explores possible ways of addressing this problem.
+In the browser, networking is supported in two ways:
+
+-   A fast transport for `wp_safe_remote_get` to translate them into `fetch()` calls.
+-   A slower transport for all other network calls that [parses the TLS transmission](https://github.com/WordPress/wordpress-playground/pull/1926) initiated by PHP and translates it to a `fetch()` call.
