(Chilkat for Android™ API)
Adding Cookies to an HTTP Request

Demonstrates how to add one or more cookies to an HTTP request. For Chilkat HTTP methods that use an HTTP request object, such as SynchronousRequest or PostUrlEncoded, cookies are added by calling the AddHeader method on the request object. For Chilkat HTTP methods that do not use an HTTP request object, such as QuickGetStr, cookies are added by calling AddQuickHeader.
