Layer2 Tunneling Protocol (L2TP) An industry-standard Internet tunneling proto col that provides encapsulation for sending Point-to-Point Protocol (PPP) frames across packet-oriented media. For IP networks, L2TP traffic is sent as User Datagram Protocol (UDP) messages. In Microsoft operating systems, L2TP is used in conjunction with Internet Protocol Security (IPSec) as a virtual private network (VPN) technology to provide remote access or router-to-router VPN connections. L2TP is described in Request for Comments (RFC) 2661.

The next example will demonstrate both a normal postback and an AJAX asynchronous (partial) post-back with two labels: one will update every time the full page updates; the other will update asynchronously. To start, create a new web site named Postbacks. If necessary, refer back to Figure 1-2, and create the new web site just as you did in the HelloWorld example, but this time select the ASP.NET AJAX-Enabled Web Site template instead of ASP. NET Web Site. Be sure to name the web site folder Postbacks, to give that name to the site. When the project is open, switch to Design view by clicking on the Design tab at the bottom of the editing surface. Because you chose the AJAX-Enabled Web Site template, you ll notice that the IDE inserted a ScriptManager control onto your page. We ll discuss the ScriptManager in detail in 3, but be assured that it will not be visible when your application is running; its job is to work behind the scenes to coordinate the AJAX controls on the page. Press the Enter key once to move the cursor below the ScriptManager control, then type in the text:

Most UI elements such as TextView widgets and Buttons display textual values. If those textual values vary in length from one language to the next which they can and often do it may be prudent to provide a locale-specific layout file in some instances. The idea here is to be intentional about your application s visual appearance rather than letting the user have a nondeterministic experience. Recall that many UI elements specify a width value wrap_content. This may not result in a visually appealing layout at runtime. If a particular string is going to distort the UI of your application, find out ahead of time and rearrange your widgets within a locale-specific layout as required. In addition to your resources, you need to consider the data values your application uses, such as date and time, numbers, and currency. This is the topic of the next section.

These days, most mail servers reject all incoming messages with executable files attached; even if the server doesn t stop such messages, modern e-mail clients make it difficult or impossible to run executable attachments . That simple measure completely stops most viruses written before 2003 . To work around the blockade, attachment-based viruses now typically send their payloads using the standard .zip format for compressed files . If the user opens the attachment, the contents of the compressed file appear in Windows Explorer or in the third-party utility assigned to handle .zip files . Double-clicking the executable file within the compressed archive sets the virus in motion . Virus writers use a variety of tricks with .zip files . In some cases, they include a bogus extension in the file name and then append a large number of spaces before the real file name extension, so that the actual file type doesn t appear in the window that displays archived files . Some viruses even encrypt the .zip attachment and include the password as part of the message . That allows the infected attachment to slip past some virus scanners . Most real-time scanners will detect a virus in a .zip file, either when it arrives or when the user tries to extract the file . The moral Be wary of all attachments, even when they appear to be innocent .

This line creates a ViewState dictionary object if it does not already exist, creates a key in the dictionary called Counter, and associates the value of 1 with Counter. When you click the Increment Counter button, the page posts back, which means that the Load event is raised, and the method is called again. The Counter item already exists in the dictionary, so its value is increased by 1. Note that if the page had a dozen buttons, clicking any of them would increment the counter, since all it takes is a postback to run the code in Page_Load.
