+<PRE>Hey there,
+
+maybe I'm missing the obvious. What I want to do is add some generic
+handler for exception handling. Say we have a set of resources some of
+which delegating stuff to external, other services. These calls might
+result in a
+
+throw({error, timeout})
+
+for instance. How would I add/modify cowboy's middleware (right place?) to
+handle those (known) exception and return a custom error (like 504 -
+Gateway Timeout).
+
+Thanks for any hints,
+
+Steve
