[BUG] Insecure HTTP urls always fail in Docker

[mattbenton]

Proxyman version

Version 2.9.1 (20910)

macOS Version

10.15.7 (19H2)

Steps to reproduce

I'm using Docker Desktop for Mac version 2.3.0.5 (48029) (stable).

1. Ensure Proxyman is closed

2. Enter container and install curl

docker run -it ubuntu:12.04 bash

3. Install curl within the container:

apt-get update; apt-get install -y --force-yes curl

4. Test without Proxyman

# This returns 200
curl -I http://example.com

# This returns 200
curl -I https://example.com

5. Open Proxyman. Ensure all tools are disabled (requests to example.com should essentially pass through). Test again while Proxyman is open:

# This should return status 200, but returns 400
curl -I http://example.com

# This returns 200
curl -I https://example.com

Expected behavior

I expect HTTP and HTTPS requests to work within Docker regardless of whether Proxyman is open, especially when the domain being requested is not configured to be processed by Proxyman.

Thanks for detailed walkthrough. I will try to reproduce the bug today and get back to you soon 👍

@mattbenton please check out this beta build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.9.1_curl_docker_issue.dmg

I tested curl -I http://example.com --proxy http://localhost:9090 from macOS, it works fine, but it doesn't work on Ubuntu Docker.

The problem was the curl in ubuntu is older (7.22.0) than the curl from macOS (7.64.1), so the HTTP Message format is slightly different. Therefore, Proxyman mistranslates it.

It's fixed and works fine now 🙌 😄

If you're using this beta build, please ignore it. I introduce another bug that causes the query of URL is absent 😣

I'm fixing it now ✊

Hey @mattbenton, this beta build should fix all cases: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.9.1_curl_docker_2.dmg

Let check it out and let me know if resolve your cases. Thank you in advance 🙌

@NghiaTranUIT Excellent! I had been testing the first beta you sent and was about to update that HTTP was not working in a particular edge case. However, the issue seems to be resolved with your newer build.

Thank you! 😄

Glad to know it finally works 😄
