Private cookie for only my app? Why is it influencing the browser's cookie?

Question

When I log into my app, my browser\'s cookie for the same site is lost. Why is this cookie being shared between apps? Logging-in in Chrome does not affect Safari\'s cookies,

Answer 1

By not using the cookie-management of the OS but implementing your own. IIRC Chrome on OSX uses an SQLite3 DB to store cookies and implements several parts of the browser/http/network communication itself.
