----------------------------------------
Summary: UrlRewriteResponse does not drop a lowercase backend
Content-Length header
Key: KNOX-3559
URL: https://issues.apache.org/jira/browse/KNOX-3559
Project: Apache Knox
Issue Type: Task
Components: Server
Affects Versions: 3.1.0
Reporter: Tamás Marcinkovics
Assignee: Tamás Marcinkovics
{{UrlRewriteResponse}} drops the backend {{Content-Length}} header because
rewriting can change the body length. The header name check is case sensitive,
so a lowercase {{content-length}} header (e.g. from OpenSearch Dashboards /
Node.js) is passed to the response. When the rewritten body is longer, Jetty
aborts the response (written N > M content-length) and the client gets a failed
request.
