Steps to Reproduce



Not Applicable.


Root Cause



Root cause of the issue is problem in PRPC code.While making the changes for HttpOnly, response.setHeader method is used to set the cookies(eg:Pega-RULES, Pega-Captcha and other cookies). This overrides the headers that are already set with the same name(SET-COOKIE).
JSESSIONID is set even before Pega-RULES cookie in the response headers.
As JSESSIONID cookie and Pega-RULES cookie both share the same headername(SET-COOKIE), the first one is getting overridden.


Resolution


Apply HFix-20419.
