A2 Proxy

Once an application is registered with an unique prefix, A2 will serve as proxy for that application. Applications can also tell A2 which routes should be forwarded through proxy and which not.

Figure 1 displays the main dependencies of A2 and the steps followed when forwarding client requests through proxy. After a request is made to A2 (step 1: request), it checks both authentication (step 2: check authentication) and authorization (step 3: check authorization) before forwarding the request (step 4: proxy request) with the authenticated user to server-side assets (step 5: proxied request with authenticated user) and get their response (step 6: proxied response).

Figure 1.: A2 dependencies and steps for authentication and authorization. After checking both, A2 uses a proxy request with the authenticated user to connect to server-side assets.
