Establishing a session

This section provides an overview of how to establish a proxy session using the Qlik Sense Proxy Service (QPS).

1. TCP Listener: The default port is 443 (HTTPS). If no other suitable certificate is available on the machine, the Qlik Sense service certificate is used to secure the request.

2. Parse incoming request:

   1. Target service: Qlik Sense Engine Service (QES), Qlik Sense Repository Service (QRS), or Qlik Management Console (QMC)?
   2. Request headers
   3. Request type: Engine, static, or dynamic content.

3. Choose virtual proxy.

4. Authentication: The following must be true. If authentication fails, you are redirected to the Authentication module:

   1. Valid ticket or any session ID: Yes
   2. Anonymous users enabled: Yes
   3. Header authentication enabled and user ID present in header: Yes
   4. Invalid ticket or no session ID and no ticket: No

5. Got session ID: If this fails, you need to get a new session module, or to validate the current one.

6. Session ID in cache: If the session ID is invalid, you are redirected to the Authentication module.

7. Perform load balancing.

8. Session is established.
