 This is desirable as it allows simple applications (such as web based applications) to interface with SteamVR without the hassle of setting up their own driver.
 
-Finally, the driver also has the ability to host a simple webserver, which serves the files in `/resources/webserver` on port 8088.  
+The driver also hosts a simple webserver, which serves the files in `/resources/webserver` on port 8088.  
 This can be accessed from: [http://localhost:8088](http://localhost:8088), which serves `/resources/webserver/index.html`.  
 
+
+The driver also hosts 3 additional pseudo-https (non-trusted certificate) webservers, which serves the files in `/resources/webserver` on port 8089/8090/8091. By sending requests to these in binary (8090 = 0, 8091 = 1, 8089 = end) you can remotely store data in the echo value on the websocket. An example of this is included in `send-echo-ssl.js`.
