Difference between "cloning" a request and "replaying" a request?

Question

I'm new to Fiddler and have run across something that seems strange to me. If I select an entry and then click Replay, I get different behavior from when I drag an entry into the Composer window and click Execute.

Should the different behavior between these two methods of re-making a request be different?

Note: I called the second method "cloning" a request because the Composer window says "You can clone a prior request by dragging and dropping a session from the Web Sessions list)."

Answer 1

What is the "different behavior" specifically?

The two operations you describe should behave the same way unless the server returns a redirect or an authentication challenge, in which case preferences will control whether Fiddler automatically authenticates and/or follows the redirect.

Please feel free to email me (Help > Send Feedback) details and/or screenshots of the difference you see.
