Does aiohttp support proxy protocol?

[mineus55]

I've been using nginx reverse proxy that redirects a domain to upstream web servers including aiohttp. There is this feature called proxy_protocol that broke request to aiohttp when enabled. Is it supported?

No, it looks like something that essentially wraps HTTP (i.e. it adds data before the HTTP message). There would need to be changes to the parsers etc. to be able to handle this, if I understand correctly (and it was actually something we wanted to support). I'm not clear what advantage this would add to aiohttp though, at a glance it doesn't look useful for a web application (seems to be more useful for VPN, firewalls or similar when bounced through a proxy).

Years ago, the Home Assistant folks tried hiring me to implement something like that. And I even looked into where it could be integrated. But then, we lost contact (I stopped getting email replies) so I didn't proceed any further. I think their use case was a reverse proxy too.
