49 \class QWebSecurityOrigin
50 \since 4.5
51 \brief The QWebSecurityOrigin class defines a security boundary for web sites.
52
53 \inmodule QtWebKit
54
55 QWebSecurityOrigin provides access to the security domains defined by web sites.
56 An origin consists of a host name, a scheme, and a port number. Web sites
57 with the same security origin can access each other's resources for client-side
58 scripting or databases.
59
60 For example the site \c{http://www.example.com/my/page.html} is allowed to share the same
61 database as \c{http://www.example.com/my/overview.html}, or access each other's
62 documents when used in HTML frame sets and JavaScript. At the same time it prevents
63 \c{http://www.malicious.com/evil.html} from accessing \c{http://www.example.com/}'s resources,
64 because they are of a different security origin.
65
66 Call QWebFrame::securityOrigin() to get the QWebSecurityOrigin for a frame in a
67 web page, and use host(), scheme() and port() to identify the security origin.
68
69 Use databases() to access the databases defined within a security origin. The
70 disk usage of the origin's databases can be limited with setDatabaseQuota().
71 databaseQuota() and databaseUsage() report the current limit as well as the
72 current usage.
73
74 For more information refer to the
75 \l{http://en.wikipedia.org/wiki/Same_origin_policy}{"Same origin policy" Wikipedia Article}.
