It is also possible to name your JavaScript page as the name of your preferred skin (see the section about skins) followed by .js, e.g. vector.js or monobook.js. JavaScript in such pages is only used while you are using that skin; should you change your skin, you would need to move the JavaScript page to the name of your new skin.
In computing, the same-origin policy (SOP) is a concept in the web-app application security model.Under the policy, a web browser permits scripts contained in a first web page to access data in a second web page, but only if both web pages have the same origin.
In the API, runtime access to the NX bit is exposed through the Win32 API calls VirtualAlloc[Ex] and VirtualProtect[Ex]. Each page may be individually flagged as executable or non-executable. Despite the lack of previous x86 hardware support, both executable and non-executable page settings have been provided since the beginning.
The various levels of protection can be applied to the page edit, page move, page create, and file upload actions. Even when a page is protected from editing, the source code of the page can still be viewed and copied by anyone. A protected page is marked at its top right by a padlock icon, usually added by the {{pp-protected}} template.
As the JavaScript code was also processing user input and rendering it in the web page content, a new sub-class of reflected XSS attacks started to appear that was called DOM-based cross-site scripting. In a DOM-based XSS attack, the malicious data does not touch the web server.
The NX bit specifically refers to bit number 63 (i.e. the most significant bit) of a 64-bit entry in the page table. If this bit is set to 0, then code can be executed from that page; if set to 1, code cannot be executed from that page, and anything residing there is assumed to be data.
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
A SPA moves logic from the server to the client, with the role of the web server evolving into a pure data API or web service. This architectural shift has, in some circles, been coined "Thin Server Architecture" to highlight that complexity has been moved from the server to the client, with the argument that this ultimately reduces overall complexity of the system.
