Another objection that has been voiced regarding cookies has to do with the fact that cookies are stored on disk so that they can be used in later visits to a Web site This kind of use of cookies is slightly different than those used for managing an application's session or state it is often used to identify returning users and to maintain a user's state Therefore, it is meaningful to distinguish between cookies used within a session and cookies stored on disk Coming back to the Security Settings dialog box, notice that you can allow cookies that are used for session management (that is, within a browser session) while disallowing persistent cookies "Conventional" Session Management Because session management is fundamental to the nature of an application, it has been around since the first applications on the Web long before the existence of servlets Many methods of maintaining sessions have evolved However, we are not providing a complete overview of all such methods, because such a discussion is not within the scope of this book In addition, we do not wish to encourage "bad habits" We believe it's best for people writing servlets to use the session management abilities that are built into the servlet API For completeness, some of the "conventional" session management mechanisms are discussed here before a "mainstream" discussion Hidden Fields Probably the oldest method for tracking session state involves hiding fields within forms Hidden fields were used in 22 when the user's name was embedded into the FastTickercom profile update screen This field was inserted by the servlet's GET processing and used by the POST update In a typical scenario, the session and state information is passed around by a set of fields hidden within forms Since all fields, whether hidden or not, are propagated from the client to the servlet in any submit 402. birt pdf 417, how to make barcode labels in word 2013, how to use code 128 barcode font in word, birt ean 128, word code 39 barcode font download, free birt barcode plugin .net upc-a reader UPC-A .
