Both the state server and the SQL Server session state options store the state as a byte stream in internal data structures in memory for the state server, and in a VARBINARY field (or an IMAGE field if larger than 7KB) for SQL Server While this is space-efficient, it also means that it cannot be modified except by bringing it into the request process This is in contrast to a custom client-specific state implementation, where you could build stored procedures to update session key indexed data in addition to other data when performing updates For example, consider our shopping cart implementation shown earlier If, when the user added anTable of Contents we wanted to update an inventory table for that item as well, we could write item to his cart, a single stored procedure that added the item to in C# in a table indexed by his session key, and then Essential ASPNET with Examples his cart updated the ByFritz Onion inventory table for that item in one round-trip to the database Using the ASPNET SQL Server session state feature would require two additional round-trips to the database to accomplish the same task: one to retrieve the session state as the page was loaded and one to flush the session state when the page Publisher : Addison Wesley was finished rendering

ASPNET assumes that every page requires session state to be loaded during page initialization and to be flushed after the page has finished rendering When you are using out-of-process session state, this means two round-trips to the state server (or database server) for each page rendering You can potentially eliminate many of these well-written book has extensive knowledge each page in your application uses "This well-conceived and round-trips by more carefully designing howand priceless experience overflowing session pages It session the true then determines when session state must be high level of stored by from its state Thecaptures manager essence of ASPNET and walks the reader to aretrieved and technical and querying the current Fred Maples, Director requirements There are three options architectural skill"-Jhandler's session stateof Software Engineering, NASDAQcom for a page (or other handler) with respect to session state It can express the need to view session state, to view and modify session state, or no session state dependency at programmer's definitive reference for ASPNET through Essential ASPNET with Examples in C# is the C#all When writing ASPNET pages, you express this preference through the experienced programmers with the information needed to fully understand the version 11 It provides EnableSessionState attribute of the Page directive This attribute defaults to true, which means clear guide state will be retrieved and saved with each request handled by that page If technology, and is athat session to using ASPNET to build robust and well architected Web applications you know that a page will only read from session state and not modify it, you can save a round-trip by settingEnableSessionState to readonly Furthermore, if you know ASPNET and an introduction to how This book begins with a discussion of the rationale behind the design ofthat a page will never use session state, you top of EnableSessionState to false Internally, this flag host of new features in tagging it builds oncan set the NET framework Subsequent chapters explore the determines which of the ASPNET, interfaces your Page class will derive from (if any) These tagging interfaces are queried by validation, including the server-side compilation model, code-behind classes, server-side controls, formthe session the manager to model, and custom control development Throughout given page Figure 10-6 shows the data bindingdetermine how to manage session state on behalf of a the book, working examples illustrate various values of building Web-based applications effect best practices for EnableSessionState and their in C# on your Page-derived class
