Support JMeter HTTP Recorder (proxy) output as input format

[davidcampbelldc]

Summary

LoadMagic needs the capability to ingest and process JMeter HTTP Recorder (proxy) output as an input format, in addition to the existing HAR file and Fiddler output support.

Background

From Testing Mavens partnership meeting (Feb 16, 2026):

• Testing Mavens' team uses the JMeter HTTP Recorder (proxy) for some projects, especially enterprise clients with proxy limitations.
• Feby George clarified that when Alex referred to "proxy" recording, they meant the JMeter HTTP recorder specifically.
• David confirmed this has been requested by many users and is feasible — the JMeter recorder's XML output can be converted to a HAR file internally, similar to how Fiddler output is already converted.
• Alex estimated that ~80% of their scripts use HAR files, but the remaining 20% using the JMeter recorder need to be supported for full adoption.

Technical Approach

• Convert JMeter HTTP Recorder XML output to HAR file format internally (similar to existing Fiddler .saz conversion pathway).
• The recorder output contains request/response data that can be mapped to HAR entries.

Acceptance Criteria

• JMeter HTTP Recorder XML output can be uploaded as an input format
• Conversion to internal HAR format works correctly
• Correlation pipeline processes the converted data as expected
• Documentation updated to list JMeter Recorder as a supported input

• Fiddler .saz recording import facility (as alternative to HAR files) #54 (Fiddler .saz recording import — same pattern of alternative input format support)
