JMeter Java (HTTPJavaImpl) for file upload requests #87
Description
Context
Some enterprise customers need JMeter to use the Java HTTP implementation (HttpClient4 / Java) instead of the default HTTPClient for specific requests — particularly file upload scenarios where the default implementation may not handle multipart uploads correctly or where proxy/security requirements mandate it.
Scope
- Investigate when Java implementation is needed vs default (typically multipart file uploads, specific auth mechanisms)
- Add capability to auto-detect from HAR when a request is a file upload and may benefit from Java implementation
- Allow user or AI to switch individual samplers to Java implementation
- Ensure correlation still works correctly with Java implementation responses
Status
Future consideration — raised from Wipro conversation. Do not start work until explicitly prioritised.
