Session Cookie missing for some URLs in app-access.log or Tomcat access log import/analyze job based data (including portlets), what can be the reason for it?
This is expected. The Session Cookie will be missing for all requests that are:
XOG/SOAP - contains the authentication in the body, not in the cookie
A bookmark used, i.e.:
If a user connects to PPM using a bookmark or link such as:
It will first direct him to the URL, then determine user is not logged on and send him to the login page.
Same happens if user was timed out and they get back to the browser and refresh the page.
Having this session cookie not defined is normal and expected at this stage.
