+== Collabora Office Load Balance
+
+Collabora uses the WOPI procotol. This protocol can be balanced by using the `WOPISrc` to send the traffic to the proper loolwsd
+server.
+
+Disable SSL of the loolwsd web service.
+
+==== loolwsd.xml
+
+```
+<enable default="true" desc="Controls whether SSL encryption between browser and loolwsd is enabled (do not disable for production deployment). If default is false, must first be compiled with SSL support to enable." type="bool">false</enable>
+ 
+<termination default="false" desc="Connection via proxy where loolwsd acts as working via https, but actually uses http." type="bool">true</termination>
+```
+
+==== HAProxy
+
+Configure HAProxy to extract the `WOPISrc` URL parameter and use it to send always the traffic to the same `loolwsd` backend.
+
+```
+Frontend loolwsdbind \*:443 ssl crt /Path to your certificate_and_key.pem
