[undertow-dev] occasional 502 from Apache HTTP Proxy

[Stuart Douglas]

Another question, are you setting a content length on the responses? If 
not the channel will automatically set one if the response fits inside a 
buffer, otherwise chunked encoding will be used.

It might be helpful to know if this only happens on chunked, fixed 
length or both.
