### Description
Hi,
first of all, thanks a lot for that great piece of software. So far the only
open source gateway that has (almost) all you need.
I am just facing one issue, that i am not sure about, if it is intended or
if i might be doing something wrong.
I am having 2 apps, with a frontend and a backend each, running under
different hosts.
These are handled in an apisisx-instance together with keycloak as idp and
oidc-plugin.
my keycloak has 2 different clients, one for App A and one for App B.
I defined rules in apisix, to use the corresponding client-id and
client-secret according to path and host.
So something like that:
```
- uri: /web/app1
hosts:
- app1.mydomain.de
plugins:
openid-connect:
client_id: ${client_id_a}
client_secret: ${client_secret_a}
discovery:
{kc_uri}/realms/{kc_realm}/.well-known/openid-configuration
realm: {kc_realm}
unauth_action: auth
logout_path: /logout
session:
secret: ${session_secret_a}
upstream:
type: roundrobin
discovery_type: dns
nodes:
"internal-web.domain.node_a": 1
1- uri: /api/*
hosts:
- app1.mydomain.de
plugins:
openid-connect:
client_id: ${client_id_a}
client_secret: ${client_secret_a}
discovery:
{kc_uri}/realms/{kc_realm}/.well-known/openid-configuration
realm: {kc_realm}
unauth_action: deny
logout_path: /logout
session:
secret: ${session_secret_a}
upstream:
type: roundrobin
discovery_type: dns
nodes:
"internal-api.domain.node_a": 1
- uri: /web/app2
hosts:
- app2.mydomain.de
plugins:
openid-connect:
client_id: ${client_id_b}
client_secret: ${client_secret_b}
discovery:
{kc_uri}/realms/{kc_realm}/.well-known/openid-configuration
realm: {kc_realm}
unauth_action: auth
session:
secret: ${session_secret_b}
upstream:
type: roundrobin
discovery_type: dns
nodes:
"internal-web.domain.node_b": 1
1- uri: /api/*
hosts:
hosts:
- app2.mydomain.de
plugins:
openid-connect:
client_id: ${client_id_b}
client_secret: ${client_secret_b}
discovery:
{kc_uri}/realms/{kc_realm}/.well-known/openid-configuration
realm: {kc_realm}
unauth_action: deny
session:
secret: ${session_secret_b}
upstream:
type: roundrobin
discovery_type: dns
nodes:
"internal-api.domain.node_b": 1
```
The behaviour i would have expected here, is that when logging into A, a
session for A is created. And when accessing B, apisix would recognize that
this is a different app with a different client and different session secret,
and therefor the session from A should not be applied here and another login is
enforced when accessing web2.
Instead i am simply also already logged in against B with the user from A.
The only way i can think of atm, to overcome this is running one apisix
instance per application, but thats propably not how it should be.. So what i
would like to have, is that a session is only valid for the client, we used for
login, or some other way to configure the scope of session-validity. Easiest
way would be to propably simply define the session-cookie name, that is checked
against. As far as i can see cookies always identify like "session=", and if
something like that is found, it is simply treated as authenticated. Using
different session-secrets also didnt do the job.
So am i missing something here, or is this intended? And if not, could this
be added? Would be a really helpful feature :)
Best regards
Robert
