+(This needs updating)
+
+Q) Is it possible to use a reverse proxies / load balancers with CLOG Apps?
+
+A) CLOG uses websockets which uses an http "upgrade" mechanism which means
+the proxy or load balancer must have some knowledge of how to handle websockets. The two most popular Apache and Nginx support it:
+
+For nginx see:
+   http://nginx.org/en/docs/http/websocket.html
+   http://nginx.com/blog/websocket-nginx/
+
+For Apache 2.4.5+ see:
+   http://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html
+
+Example of CLOG application as its own domain:
+
+<VirtualHost *:80>
+    ServerName snake.clog.com
+    ServerAdmin david@botton.com
+
+    ProxyPass /clog ws://127.0.0.1:8080/clog
+    ProxyPass / http://127.0.0.1:8080/
+    ProxyPassReverse / http://127.0.0.1:8080/
+
+    ErrorLog ${APACHE_LOG_DIR}/clog.err.log
+    CustomLog ${APACHE_LOG_DIR}/clog.log common
+</VirtualHost>
+
+Example of a CLOG application as a subdirectory on a larger site using Apache:
+
+<VirtualHost *:80>
+    ServerName clog.com
+    ServerAlias www.clog.com
+    ServerAdmin david@botton.com
+    DocumentRoot /www/clog
+
+    ProxyPass /snake http://127.0.0.1:8080
+    ProxyPassReverse /snake http://www.clog.com:8080
+    ProxyPass /clog ws://www.clog.com:8080/clog
