What are the steps to reproduce the problem?

Run http --follow --print=H pie.dev/redirect/3

What is the expected result?

I should only see the ~~last~~ first request header

What happens instead?

Intermediate request headers are shown but there is no mention in the docs that --print implies --all

Hello @ducaale,

Thanks for the report.

After digging into the issue, it appears to be a little bit complicated to handle that scenario. I do not say we will not fix it, but it requires to adapt how requests are printed and we like the way it is as of now: streamed in real-time. I simply added a reproduction test case with 9792513c6878a410fe7645810668f820100b5eea and delayed the work on a potential solution for now because we have more important priorities.

Just keep the issue open and we will come back in the future with a solution :)

I should only see the last request header

Hm, would you expect to only see the last request? That's how --all is documented, but seeing only the first request and the final response is what I'd intuitively expect.

(Context: we're implementing --all in ducaale/xh#137 and aren't sure about the correct behavior)

[ducaale]

seeing only the first request and the final response is what I'd intuitively expect.

This is how https://github.com/ducaale/xh/pull/137 is currently being implemented

• By default, the first request and last response are printable
• --all can mark intermediate responses and requests as printable
• --print affects any request and response that is marked as printable
• --history-print affects intermediate requests and responses which are marked as printable
• --verbose implies --all

I am not sure why I said last request instead of first request in the bug report .
