----------------------------------------
Summary: camel-netty-http - key multiplex channel handlers by
listener address
Key: CAMEL-26065
URL: https://issues.apache.org/jira/browse/CAMEL-26065
Project: Camel
Issue Type: Bug
Components: camel-netty-http
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.24.0, 4.22.3, 4.18.6
h3. Current behaviour
{{NettyHttpComponent}} maintains server listening sockets
({{HttpServerBootstrapFactory}}) per host and port address, but keeps consumer
multiplex channel handlers ({{HttpServerConsumerChannelFactory}}) in a map
keyed solely by integer {{port}}.
When multiple {{netty-http}} consumers share a port on different host addresses:
* {{HttpServerInitializerFactory}} and {{HttpServerBootstrapFactory}} install
the per-port multiplex channel handler into each server pipeline.
* Inbound requests on any listening socket on that port are matched by
{{HttpServerMultiplexChannelHandler}} against all consumers registered on that
port across all host addresses.
h3. Expected behaviour
{{NettyHttpComponent}} keys multiplex channel handlers by the listener's
address (host:port), ensuring that each listening socket dispatches requests
only to consumers bound to its own address.
h3. Change
* {{NettyHttpComponent}}: Key {{multiplexChannelHandlers}} by listener address
string (host:port). Add {{getMultiplexChannelHandler(String address)}} and
retain {{getMultiplexChannelHandler(int port)}} as deprecated for backwards
compatibility.
* {{HttpServerInitializerFactory}}: Retrieve the multiplex channel handler
using {{consumer.getConfiguration().getAddress()}} instead of port alone.
* {{HttpServerBootstrapFactory}}: Initialize using the address-based multiplex
channel handler.
h3. Tests
* {{NettyHttpDifferentHostSamePortTest}}: Verify that consumers configured on
the same port across different host addresses only receive requests directed to
their respective listening sockets, returning 404 for paths registered only on
another host address.
