Use WebProxy with msal4j

Question

Our daemons application is using msal4j 1.3 to get access token from https://login.microsoftonline.com/. However, in some of our customer's production environment, it is not possible to access https://login.microsoftonline.com directly. They want to use authenticated proxy to access it. Is it possible to set have msal4j to use a webProxy? If not, what is the suggestion for us to use msal4j with such a webProxy?

Answer 1

Yes, you can have MSAL4J use a Proxy.

The most straightforward way would be by injecting the Http client that the application is using into MSAL. You would configure the proxy settings on the Http client, implement MSALs IHttpClient, and then pass in the implementation into MSAL when you instantiate the client application object. MSAL will then use this Http client for all requests. For more information, see the Configure Http Client wiki page
