2. How I run Caddy:

sudo caddy run # via a Caddyfile

a. System environment:

$ uname -a

Use `caddy fmt` to make it readable.
DO NOT REDACT anything except credentials.
LEAVE DOMAIN NAMES INTACT.

3. The problem I’m having:

I want to have two upstreams for my reverse proxy. The issue is, one of them has a path, and the other doesn’t. Like upstream1.com and upstream2.com/path/subpath . Also, one of them is HTTP, and the other is HTTPS.

All the comms are done via POST requests. So, requests don’t have paths. The reason upstream 2 uses a path is as an API key. Is there a way to load balance across these upstreams via Caddy?

4. Error messages and/or full log output:

Paste logs/commands/output here.
USE THE PREVIEW PANE TO MAKE SURE IT LOOKS NICELY FORMATTED.

5. What I already tried:

I don’t understand… you want Caddy to load balance between two upstreams that don’t accept requests in an identical way?

That doesn’t quite make sense to me.

Load balancing is almost always done to identical or near-identical servers (from an HTTP traffic standpoint).

Please completely fill out the help topic template. We’re missing a lot of key information here, I think.

Hey @francislavoie ,

That’s correct. One accepts HTTP, the other HTTPS. The one uses upstream1.com, the other uses upstream2.com/path . Is that possible at all?

No it’s not possible. The transport config is not per-upstream, and neither is rewrite config.
