Backend

Backend server url.

Name	Type	Env	Values	Default	Description

Proxy

Proxy allows you to forward requests to other servers based on the request path.

Name	Type	Env	Values	Default	Description
Admin	string		url		Url to admin server
Api	string		url		Url to api server

If you use another mount point on the admin server you must setup the same proxy path here. In the cradle-cms container we have the admin server behind the frontend server using proxy path forwarding. We also make use of TrustProxy="X-Forwarded-For" on the admin server.

Example

[frontend.Proxy]
admin = "http://127.0.0.1:8888/admin"
api = "http://127.0.0.1:8888/api"

Persist	bool	SESSION_PERSIST		false	Persist session cookie
Secure	bool	SESSION_SECURE		true	Secure session only (tls)
HttpOnly	bool	SESSION_HTTP_ONLY		true	Http only

If you allow http access to you site you must set Secure to false or the cookie won’t be sent by the browser.
