INTERNET-UNIFORME RESOURCE LOCATOR

URL, c’est quoi ?

Adresse Internet exploitée par les navigateurs (Internet Explorer ou Navigator, par exemple). C’est l’adressage standard de n’importe quel document, sur n’importe quel ordinateur en local ou sur Internet.
Structure de base d’une URL :
protocole://serveur/répertoire/document.extension
http://caensortir.com

Hyperliens

Les liens, vous connaissez, puisque vous avez déjà plusieurs fois cliqué pour parcourir ces pages. Mais si vous savez utiliser, vous ne savez peut-être pas faire, ou faire correctement.
Rappelons pour commencer qu’un lien (hyperlien, on dit aussi lien hypertexte) est un élément sur lequel on clique pour ouvrir une nouvelle page. Quand on passe la souris dessus, le pointeur prend la forme d’une main. On peut le taper à la main dans le code source, par une balise du type <a href=”…., mais pourquoi se fatiguer et risquer de commettre une erreur quand les programmes font ça tout seuls ? Un hyperlien peut aussi être construit de façon externe au document lui-même, dans une base de données référençant toutes les paires (URL source, URL cible) entre une zone activable d’un document source et une ancre cible dans un document (qui peut être le même que le document source contenant la zone activable).
L’hyperlien peut aussi être construit de façon inversée, en insérant dans le document cible l’URL de la zone source.

Barre d’adresse

Chaque navigateur web dispose d’une « barre d’adresse » affichant l’URL de la ressource consultée. Il est en outre possible de saisir une URL dans cette barre d’adresse pour consulter une ressource dont on connaît l’URL. On peut aussi trouver l’url en positionnant la souris sur l’image ou le texte approprié .

Historique de navigation

Les navigateurs web conservent un historique des URL consultées. Cela leur permet de reconnaître et présenter de manière distinctive les hyperliens vers des ressources déjà consultées.

Pages favorites

Il suffit à un navigateur web de conserver l’URL d’une ressource pour constituer une liste de favoris (ou marque-pages). Lorsqu’un titre de ressource existe, les navigateurs le conservent aussi, ce qui permet d’afficher le titre d’une page plutôt que son URL.

Fonctionnement

Une URL est une chaîne de caractères combinant les informations nécessaires pour indiquer à un logiciel comment accéder à une ressource d’Internet. Ces informations peuvent notamment comprendre le protocole de communication, un nom d’utilisateur, un mot de passe, une adresse IP ou un nom de domaine, un numéro de port TCP/IP, un chemin d’accès, une requête.
Les informations nécessaires varient selon la ressource et le contexte d’utilisation de l’URL. En outre un identificateur de fragment peut être ajouté à la fin d’une URL pour identifier un élément à l’intérieur de la ressource. Bien que l’identificateur de fragment ne fasse pas formellement partie de l’URL, il est également décrit dans cet article et dans les standards techniques.

URL absolues et relatives

Lorsque vous entrez une URL dans le panneau URL, vous pouvez spécifier une URL absolue ou relative : * Si vous établissez un lien vers une page Web n’appartenant pas à votre site, vous devez spécifier une URL absolue.
* Par contre, si vous établissez un lien vers une page Web figurant dans votre site, vous pouvez spécifier une URL absolue ou relative.

Les URL absolues sont des adresses URL complètes, incluant le protocole de serveur (qui est généralement http:// pour les pages Web). Par exemple, http://www.macromedia.com/fr/support est l’URL absolue de la page Web du Centre d’assistance de Macromedia Fireworks. Les URL absolues restent précises, quel que soit l’emplacement du document source, mais le lien est rompu si le document cible est déplacé.

Les URL relatives sont indiquées par rapport au dossier contenant le document source. Les exemples suivants présentent la syntaxe de navigation d’URL relatives :

* fichier.htm établit un lien avec un fichier situé dans le même dossier que le document source.
* ../../fichier.htm établit un lien avec un fichier situé dans un dossier placé deux niveaux au-dessus du dossier contenant le document source. Chaque signe ../ représente un niveau.
* htmldocs/fichier.htm établit un lien vers un fichier situé dans un dossier appelé htmldocs, figurant dans le dossier contenant le document source.

Les URL relatives sont généralement les plus simples pour établir un lien avec un fichier qui restera toujours placé dans le même dossier que le document actif.
