----------------------------------------
Summary: camel-platform-http - any path starting with "proxy"
selects HTTP proxy mode
Key: CAMEL-24455
URL: https://issues.apache.org/jira/browse/CAMEL-24455
Project: Camel
Issue Type: Bug
Components: camel-platform-http
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.23.0
{{PlatformHttpEndpoint.isHttpProxy()}} tests {{path.startsWith(PROXY_PATH)}}
where {{PROXY_PATH = "proxy"}}, rather than comparing for equality. Any
endpoint whose path begins with those five characters - {{proxyStats}},
{{proxy-health}}, {{proxying}} - is treated as the documented
{{platform-http:proxy}} endpoint.
The consequences chain: {{getPath()}} returns {{"/"}} for such an endpoint,
making it a catch-all, and {{VertxPlatformHttpConsumer.handleProxy()}} sets
{{Exchange.HTTP_HOST}} from the request's own {{Host}} header so that a
bridging producer forwards there.
A route author naming an endpoint {{proxyStats}} therefore gets a catch-all
whose forward target comes from the caller, which is not what the name suggests.
Proposal: compare the path for equality with {{PROXY_PATH}} (allowing a leading
slash), so proxy mode is selected only by the documented path. Needs an
upgrade-guide entry for anyone relying on the prefix match.
