[BUG] The Connection is not reused ❌

[NghiaTranUIT]

Description

• on macOS:

1. The first connection will create a Proxy Connection (Method = CONNECT)
2. After that, the client will reuse the connection (If Proxy-Connection: keep-alive is presented on the Connect Request)
3. See the video: It demonstrates that Subsequent requests will re-use the connection without creating a new

• On the main branch of Windows/Linux

1. The first connection will create a Proxy Connection (Method = CONNECT)
2. Subsequent requests don't re-use the current connection. It always creates a new one -> It's a bug ❌

Steps to Reproduce

1. Enable the SSL Proxying on httpbin.proxyman.app. Disable all tools.
2. Use insomnia to make a request to Proxyman
3. Make Subsequent requests (don't close the Insomnia app) -> Open the Raw Tab -> Check if the connection is reused or not

Current Behavior

• Insomnia always creates a new connection to Proxyman without reusing the exist tunnel -> It seems the connection is closed. Thus, Insomnia make a new connection (CONNECT request, then the real Request)

Expected Behavior

• Behave as Proxyman macOS does: Reuse the connection.

Environment

• App version:
• Windows/Linux version:
