Extension:Iframe

Copyright & security issues
Embedding external webpage into MediaWiki has two issues:


 * Copyright violation: Embedding an external web page may violate copyrights. So, make sure that the domains that can be used in the extension are trusted!
 * Security issue: External web pages may contain malicious code. Again make sure that the domains that can be used in the extension are trusted!

The extension uses keys to select web servers which are given by the wiki administrator during installation. Therefore, behind the key should only be trusted domains.

Known problems

 * The extension does not work properly with the MobileFrontend extension.

Width and height of an iframe

If no width and height is given then these defaults are used.

Delay of iframe loading
Usually a HTML document is shown if all parts of a document are loaded. If a iframe on a server, e.g. a Shiny server, triggers a lengthy computation then the document will appear only after all iframe(s) are loaded. Therefore a delay mechanism with JavaScript is included which starts the loading of the iframe(s) only after the document is ready. By  the delay is controlled:


 * 1) If in    (or any negative value) is set then the iframe(s) will be loaded immediately, no delay  will take place.
 * 2) If in    (the default) is set then the first iframe will be loaded 100 ms after the document is loaded, the second 200 ms, and so on.

Examples
1. Shows the test page of my shiny server

3. As 2., but the iframe window has only VGA size (640x480).
