Following are the popular ways of session tracking:
a.) URL rewriting: In this method of session tracking, some extra data is appended at the end of the URL, which identifies the session. This method
is used for those browsers which do not support cookies or when the cookies are disabled by the user.
b.) Hidden Form Fields: This method is similar to URL rewriting. New hidden fields are embedded by the server in every dynamically generated form
page for the client. When the form is submitted to the server the hidden fields identify the client.
c.) Cookies: Cookie refers to the small amount of information sent by a servlet to a Web browser. Browser saves this information and sends it back to the server when requested next. Its value helps in uniquely identifying a client.
d.) Secure Socket Layer (SSL) Sessions
