Bug ID: 69900
Summary: Behaviour Change After Upgrade from Apache 2.4.57 →
2.4.62 (Content-Length Dropped, Forced Chunked
Encoding)
Product: Apache httpd-2
Version: 2.4.62
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: Core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hey Team,
We recently upgraded Apache HTTP Server from 2.4.57 to 2.4.62 and observed a
behaviour change that is impacting our downstream clients.
Our Setup
Apache → Tomcat → our_web_service
Our web service explicitly sets a Content-Length header.
In some cases (e.g., binary file responses), it sets a large value such as
999999999.
In other cases, it sets a smaller value such as 161.
Issue Observed
After upgrading to version 2.4.62, Apache appears to drop the Content-Length
header and instead switches the response to Transfer-Encoding: chunked.
This change is causing issues for some of our legacy clients that rely on the
presence of the Content-Length header and do not support chunked encoding.
Request for Guidance
Is there a configuration or directive that would allow Apache 2.4.62 to
preserve the original Content-Length header from the upstream application,
maintaining backward-compatible behaviour? We would like Apache to avoid
converting these responses to chunked encoding if possible.
Any insights or recommended configuration changes would be greatly appreciated.
Thank you.
