Yaron A commented on CAMEL-7884:
--------------------------------
I got this exception on every POST request I issued using several HTTP clients
(browser, Spring's RestTemplate) and also Camel's ProducerTemplate.
I'm using netty-http both as the HTTP server and also as a HTTP client (my app
is a proxy service) and the exception is being thrown after the HTTP client
response is received.
Please guide me if the original POST request is what you need or the request
that camel-netty4-http issues?
thx
