URLs in external links

A link in external link style can be of the forms:

- target: http://meta.wikimedia.org/ is rendered as http://meta.wikimedia.org/

- [ target label ], with a blank space in between: wikimedia gives wikimedia (see also )

- [ target ] - these are automatically labelled with serial numbers 1, 2, 3, ...: gives [http://meta.wikimedia.org/

The target is a URL which can start with "http://" or "ftp://"; "file://" does not work by default. If enabled it only works in MSIE. To enable it, add a $wgUrlProtocols entry to LocalSettings.php; see the $wgUrlProtocols in DefaultSettings.php for example. All Help:Special characterss of the URL must be among: A-Z a-z 0-9 ._\/~%-+&

?!=()@

If a URL contains a different character it should be converted; for example, ^ has to be written %5e, the hexadecimal ASCII value with a percent sign in front. A blank space can also be converted into an underscore. Conversion: "

$ % & '
- , : ; < > ? [ ^ ` { | }

%22 %23 %24 %25 %26 %27 %2a %2c %3a %3b %3c %3e %3f %5b %5e %60 %7b %7c %7d For the other characters either the code or the character can be used in internal and external links, they are equivalent. The system does a conversion when needed. E.g. %C3%80_propos_de_M%C3%A9ta is rendered as %C3%80_propos_de_M%C3%A9ta, almost like À propos de Méta, which leads to this page on Meta with in the address bar the URL http://meta.wikipedia.org/wiki/%C3%80_propos_de_M%C3%A9ta while http://meta.wikipedia.org/wiki/À_propos_de_Méta leads to the same.

URLs of pages within the projects

See . On other projects everything works the same, except that the domain names vary:

- xx.wikipedia.org with xx the language code, see

- meta.wikimedia.org (meta.wikipedia.org redirects there)

- xx.wiktionary.org

- xx.wikiquote.org

- xx.wikibooks.org

- wikisource.org

- he.wikisource.org

- sep11.wikipedia.org

A URL starting with www.wikipedia.org redirects to the corresponding one starting with en; only www.wikipedia.org itself leads to a portal page instead of the main page of the English : http://www.wikipedia.org In projects outside Wikimedia the "w/" in URLs like http://www.wikipedia.org/w/wiki.phtml?title=Main_Page&action=history is sometimes not used, sometimes different, e.g.:

- http://www.disinfopedia.org/wiki.phtml?title=Disinfopedia_Main_Page&action=history

- http://wikitravel.org/en/index.php?title=Main_Page&action=history

The default is /wiki/wiki.phtml, with in DefaultSetting.php [http://cvs.sourceforge.net/viewcvs.py/wikipedia/phpwiki/newcodebase/DefaultSettings.php?rev=1.21&view=markup]: $wgScriptPath = "/wiki"; $wgScript = "{$wgScriptPath}/wiki.phtml"; There may be other variations, compare:

- http://en.wikipedia.org/wiki/Vancouver

- http://wikitravel.org/en/Vancouver

Use in templates

For use in templates, note that all URLs on e.g. the English can be written in the form http://en.wikipedia.org/w/index.php?title= This requires to be written with underscores and escape codes (if applicable). To benefit from the conversion carried out by localurl, two parameters are needed: http://en.wikipedia.org (see ). An example with the second parameter in localurl fixed is . This works for a link in external link style to a page in the same project or a project which uses the same string in the URL between the server name and the question mark ([http://www.mediawiki.org/wiki/Help:$wgScript $wgScript], on Wikimedia "/w/index.php"), but not for links to other projects.

Old versions of pages

All old versions of all pages are numbered (with oldid) approximately in the order of becoming an old version, i.e. in chronological order of the next edit of the same page.

- http://meta.wikimedia.org/w/wiki.phtml?title=Help:Link&oldid=53587 - normal link to old page

- http://meta.wikimedia.org/w/wiki.phtml?oldid=53587 - no page name in the URL, goes to the correct page

- http://meta.wikimedia.org/w/wiki.phtml?title=Help:Link&oldid=53588 - number and name do not correspond; the name is ignored

- http://meta.wikimedia.org/w/wiki.phtml?title=abc&oldid=53587 - non-existing page name; oldid is ignored, works like going to a non-existing page, except for the links to assumed previous and next versions, and on editing, for the warning of editing an old version of a page.
