OIDCRedirectURI in a Reverse Proxy Setup

[bendercodes]

So when using this module in a reverse proxy setting, where the reverse proxy is proxying requests to different services using an Authorization grant, e.g:

OIDCClientID "DummyId"
OIDCCryptoPassphrase "DummyPass"
OIDCRedirectURI https://example.com/redirect/oidc
/... more unrelated settings

<Location "/serviceA">
  AuthType openid-connect
  Require valid-user
</Location>

<Location "/serviceB">
AuthType openid-connect
  Require valid-user
</Location>

<Location "/serviceC">
  /... completely different legacy auth not using this module
</Location>

1. Can we have a single generic redirect URI (OIDCRedirectURI https://example.com/redirect/oidc) or does it need to be at the directive level (e.g. OIDCRedirectURI https://example.com/serviceA/redirect)

2. Do we have to create a dedicated Location directive for the redirect URI or is it sufficient to just list it as part of the configuration, e.g.:

<Location "/redirect/oidc">

Thank you in advance and I'm happy to submit a PR updating the FAQs if it's helpful for anyone else.

as the docs mention, it needs is to be protected by mod_auth_openidc so it can be anything that lives under AuthType openid-connect
