Thank you for the reply Jonathan.

My intentions are not malicious. The site in question is http://turkopticon.differenceengines.com/ and to read reports on that site one has to be logged in. The site is incredibly slow and I had an idea to cache the review data so reports on "bad requesters" (mturk requesters) will be easily available for access.

However using my account to proxy reviews and cache them, has resulted in someone changing my password. Nothing was lost, but to cache pages and make them available for everyone I need a way to hide the Set-Cookie session from everyone or else it exposes my account.

The site isn't really "private" but the reviews are password protected to encourage user registration.
