+    ### When you pass though potentially another reverse proxy/load balancer
+    ### in front of tpotce you can introduce more headers than normal and
+    ### therefore you can exceed the allowed header buffer of 1k.
+    ### An 280 extra bytes seems to be working for most use-cases.
+    ### And still keeping it close to OWASP's recommendation.
