Weird problem with Android emulator

[swood]

Hi everyone.

I'm trying to configure ATS as a squid (because squid doesn't support WebSocket protocol). However, I faced a problem when my desktop browser can work via ATS but doesn't work with the android emulator.
I ran ATS with debugging and saw log below:

I found the main difference between ATS and Squid. As I mentioned, Android expects something that ATS didn't provide.
The answer from ATS looks like (in tcpdump level) like below:
http://prnt.sc/nj3r0y
And the answer from Squid looks dramatically different:
http://prnt.sc/nj5e29

I can't affirm this a cause of my problem, but may I ask is there a way to change it? I mean, to make it similar as squid answer?

If you want to remove or modify headers, you may be able to do it with header_rewrite plugin.
https://docs.trafficserver.apache.org/en/8.0.x/admin-guide/plugins/header_rewrite.en.html

But I'm not sure at all. I've never used CONNECT method.

@swood is this still and issue? If so please reopen
