HTML pages, the browser makes a set of requests for smaller and more speci c pieces of information These requests look much like Web Services calls Without making an effort to prevent it, many Ajax implementations leave the door open for attackers to steal data using these calls: we term this attack JavaScript hijacking The X in Ajax is a bit deceptive Instead of XML, a large number of Ajax applications communicate using JavaScript syntax, the most popular form of which is JavaScript Object Notation (JSON) Unless they implement speci c countermeasures against it, many Web applications that transport data using JavaScript syntax allow attackers to read con dential data using a technique similar to the one commonly used to create mash-ups Normally, Web browsers enforce the Same Origin Policy in order to protect the con dentiality of user data The Same Origin Policy requires that, in order for JavaScript to access the contents of a Web page, both the JavaScript and the Web page must originate from the same domain Without the Same Origin Policy, a malicious website could serve up JavaScript that loads sensitive information from other websites using a client s credentials, cull through it, and communicate it back to an attacker JavaScript hijacking allows the attacker to bypass the Same Origin Policy in the case that a Web application serves up JavaScript to communicate con dential information The loophole in the Same Origin Policy is that it allows JavaScript from any website to be included and executed in the context of any other website Even though malicious site cannot directly examine any data loaded from a vulnerable site on the client, it can still take advantage of this loophole by setting up an environment that allows it to witness the execution of the JavaScript and any relevant side effects it may have This is not a problem for non-Ajax web sites because they generally don t communicate con dential data in JavaScript The code in Example 1010 implements the client-side of a legitimate JSON interaction from a Web application designed to manage sales leads (Note that this example is written for Mozilla-based browsers).

We start by defining shorthand names for the size_types that we'll need in our implementation Thinking ahead, we can see that the underlying data will still be a vector<string>, so the size_type member of vector<string> will be the right type to represent the height of a picture, and the ne from string will be the one we need for the width We'll abbreviate these types as ht_sz and wd_sz respectively The other task is to define our virtual functions for the base class, which you'll notice take a new form: In each case we say = 0 where the body would appear This syntax indicates our intention that there be no other definition of this virtual function Why did we define these functions this way To answer this question, let's begin by thinking about what the definitions would look like if we tried to write them In our design, Pic_base exists only to act as the common base class for our concrete picture classes We will create objects of these concrete types as a result of executing one of the Picture operations, or in response to a user's creating a Picture from a vector<string> None of these operations directly creates or manipulates Pic_base objects If there are never any Pic_base objects, then what would it mean to take the height or width of a Pic_base object (as opposed to doing so for an object of a type derived from Pic_base) These operations are needed only for the derived classes, in which there always will be a concrete picture For a Pic_base itself, there is nothing of which to take the height or width Instead of forcing us to concoct an arbitrary definition for these operations, the C++ language lets us say that there will be no definition for a given virtual function As a side effect of declining to implement the virtual function, we also promise that there will never be objects of the associated type There may still be objects of types derived from this type, but there are no objects of its exact type The way that we specify that we don't intend to implement a virtual function is to say = 0, as we did on height, width, and display Doing so makes it a pure virtual function By giving a class even a single pure virtual function, we are also implicitly specifying that there will never be objects of that class Such classes are called abstract base classes, because they exist only to capture an abstract interface for an inheritance hierarchy They are purely abstract: There are no objects of the base class itself Once we give a class any pure virtuals, the compiler will enforce our design by preventing us from creating any objects of an abstract class.
