tests/integration/test_record_modes.py:43: AssertionError

The test code already removes some headers which may differ between requests but the difference shown above is in r1.content and I don't know what the best way is to ignore X-Amzn-Trace-Id there.

It seems as if httpbin.org uses Amazon's Elastic Load Balancing which adds a unique X-Amzn-Trace-Id header. That header is different for each request.

This is because httpbin has moved hosting providers.

It makes sense to me for us to either:

• Strip it or
• Start using pytest-httpbin

Either way, contributions will be necessary for this as I'm not able to spend a significant amount of time on this.
