1. Caddy version (caddy version):
Caddy1
2. How I run Caddy:
Docker image running caddy behind a proxy
a. System environment:
Unix, Docker
b. Command:
Internally within the docker entrypoint
/bin/caddy -conf /etc/company/caddy/Caddyfile -log stdout
c. Service/unit/compose file:
Unknown
d. My complete Caddyfile or JSON config:
(disable-cors) {
header_downstream -Access-Control-Allow-Credentials
header_downstream -Access-Control-Allow-Origin
}
:80 {
errors stdout
log / stdout "[{when}] [PROXY] {remote} {method} :80{uri} {proto} [{status}] - {latency_ms} ms - {size} bytes - {upstream}"
tls off
import healthcheck
import internal-test-proxy
}
(internal-test-proxy) {
proxy /test/internal https://<custom_url_forward_connection>/ {
import disable-cors
}
3. The problem I’m having:
Currently we receive requests to this Caddy and the requests are forwarded to the proxy location. I had a look through the documentation without luck and was wondering if there is an approach or way to receive a request into Caddy but send 2 requests out to two different services. eg.
POST ServiceA: (Header X)
RequestA ->
POST ServiceB: (Header Y, Header Z)
These requests should just be forwarded and don’t request any status update except Caddy returning a 200.
Requester Log:
SENT POST Sent HTTP Request to http://caddy-proxy.internal:80
RECV STATUS 200 OK
ServiceA Log:
RECV POST Sent HTTP Request to https://service-a.internal:1234
{ headers: [ header-x: abc ] }
ServiceB Log:
RECV POST Sent HTTP Request to https://service-a.internal:5678
{ headers: [ header-y: abc, header-x: abc ] }
4. Error messages and/or full log output:
5. What I already tried:
Using reverse_proxy but this only sends it to 1 of the destinations and not all of them
6. Links to relevant resources:
Any ideas if this can be accomplished with Caddy?
