Netty HTTP Component

Available as of Camel 2.12

The netty-http component is an extension to Netty component to facilitiate HTTP transport with Netty.

This camel component supports both producer and consumer endpoints.


Netty is stream based, which means the input it receives is submitted to Camel as a stream. That means you will only be able to read the content of the stream once.
If you find a situation where the message body appears to be empty or you need to access the data multiple times (eg: doing multicasting, or redelivery error handling)
you should use Stream caching or convert the message body to a String which is safe to be re-read multiple times.

Maven users will need to add the following dependency to their pom.xml for this component:

    <!-- use the same version as your Camel core version -->
