### Issue description
I want have two upstream , if one return error, it colud fallback to the other upstream,
For example :
client request http://aa.bb.com/test default backend is proxy_pass to **http://10.100.22.11**, if it return error or healthcheck error , the request should fallback to **https://cc.dd.com**, note that the first is http ,the second is https,
so what should i do for it?
### Environment
- apisix version (cmd: `apisix version`):
- OS (cmd: `uname -a`):
- OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`):
- etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API):
- apisix-dashboard version, if have:
- the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
- luarocks version, if the issue is about installation (cmd: `luarocks --version`):

@Chever-John @starsz Thanks for reply, please note the default backend is http protocal , falback to https protocal, as my understand the node priority have to keep same protocal ,right ? Thants means we can't write like
"nodes": [
{"host": "**http**://127.0.0.1", "port": 1980, "weight": 2000},
{"host": "**https**://10.100.22.33", "port": 1981, "weight": 1, "priority": -1}
],
right ?

Hi @purekeeper.
You can set `https://cc.dd.com/` with negative priority.
> As the default priority is 0, we can configure nodes with negative priority as the backup.
Refer to the doc: https://apisix.apache.org/docs/apisix/admin-api

If I understand you correctly, I think [this](https://apisix.apache.org/docs/apisix/admin-api/#:~:text=https%20is%20valid.-,Note%3A,-Each%20node%20can) is what you mean.
Just to validate my idea.
Thinks!
