+Authproxy is part of middleend and it exposes following 3 apis
+1. **/v1/login**
+ - Redirects user to keycloak login page.
+ - Sets a cookie with original URL
+2. **/v1/callback**
+ - After successful login gets auth code and exchange it for token.
+ - Set id_token and access_token in cookie and redirects to original URL
+3. **/v1/auth**
+ - Retrieve idtoken from cookie and verifies the JWT.
+ - If id_token is valid then access to resources else redirects to login page.
+
+Required inputs of authproxy comes from authproxy section of helm config
+- Issuer
+- Redirect URI
+- Client id
