Disable the logged in cookie

Hi everybody,

i use Plone with Sentry. Everytime Sentry get an Issue from Plone the HTTP-Cookie with ac (example: __ac="NjE2NDZkNjk2ZTMyOjcyNzQ3NjQxNjQ2ZDY5NmUzNjM2MzczNw%253D%253D) is visible in to everybody who is logged in in Sentry. Is there anyway to disable or encrypt the HTTP-Cookie or only the __ac ?

Excuse me with my poor english. I try to get better.

Many thanks for you answers.

kind regards
