Gr\u00e2ce \u00e0 de nombreux plugins WordPress, non seulement WordPress peut \u00eatre \u00e9tendu par de nombreuses fonctions, mais le temps de chargement peut \u00e9galement \u00eatre r\u00e9duit de mani\u00e8re significative.<\/p>\n<p>Comme <a href=\"https:\/\/webhosting.de\/fr\/les-avantages-de-lhebergement-de-sites-web-en-mode-cloud-flare-im-web-et-ce-quil-vaut-la-peine-de-savoir\/\">CDN<\/a> est un r\u00e9seau de serveurs distribu\u00e9s r\u00e9gionalement qui sont utilis\u00e9s pour stocker de gros fichiers m\u00e9dia (vid\u00e9os, images, scripts). En ce qui concerne YouTube, par exemple, on peut parler de CDN, puisque les vid\u00e9os sont situ\u00e9es sur de nombreux serveurs dans le monde entier et sont mises \u00e0 disposition via un r\u00e9seau de diffusion de contenu (CDN).<\/p>\n<p><strong>Cependant, le principe du CDN n'est pas seulement utilis\u00e9 pour les vid\u00e9os, mais aussi pour les fichiers<\/strong>qui peuvent \u00eatre livr\u00e9s \u00e0 l'aide du syst\u00e8me de cache. Cela comprend les fichiers JPG, GIF, JavaScript ou HTML. Pour que les fichiers n'aient pas \u00e0 \u00eatre t\u00e9l\u00e9charg\u00e9s depuis votre propre serveur, ils peuvent \u00e9galement \u00eatre stock\u00e9s dans le CDN, ce qui permet d'\u00e9conomiser du trafic et de pr\u00e9server les ressources du serveur tout en maximisant les requ\u00eates du navigateur.<\/p>\n<h2>Mise en place du CDN - premi\u00e8res \u00e9tapes<\/h2>\n<p>Afin de cr\u00e9er votre propre CDN, certains pr\u00e9paratifs doivent \u00eatre effectu\u00e9s \u00e0 l'avance. Comme dans la plupart des cas, il est \u00e9galement n\u00e9cessaire de mettre en place votre <a href=\"https:\/\/webhosting.de\/fr\/eine-eigene-webseite-fuer-ihr-unternehmen-ja-oder-nein\/\">site web<\/a> y compris la base de donn\u00e9es SQL, car si quelque chose ne va pas ou ne fonctionne pas comme souhait\u00e9, l'ancien \u00e9tat du site WordPress peut facilement \u00eatre restaur\u00e9 gr\u00e2ce \u00e0 la sauvegarde.<\/p>\n<p><strong>Pour garantir le bon fonctionnement du CDN de la page WordPress et \u00e9viter toute interruption majeure, certaines informations doivent \u00eatre obtenues \u00e0 l'avance<\/strong>.<\/p>\n<p>Cela comprend la configuration du sous-domaine, la d\u00e9termination du chemin absolu du serveur du sous-domaine, le d\u00e9placement des fichiers de la m\u00e9diath\u00e8que vers le sous-domaine, la mise \u00e0 jour de la base de donn\u00e9es SQL de la page WordPress, le r\u00e9glage des param\u00e8tres de WordPress et l'information des moteurs de recherche sur la structure modifi\u00e9e.<\/p>\n<h2>Avantages d'un CDN<a href=\"https:\/\/webhosting.de\/wp-content\/uploads\/2017\/03\/browser-77.png\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-2517 alignright\" src=\"https:\/\/webhosting.de\/wp-content\/uploads\/2017\/03\/browser-77.png\" alt=\"CDN\" width=\"224\" height=\"224\" \/><\/a><\/h2>\n<p>Un r\u00e9seau de diffusion de contenu est particuli\u00e8rement utile pour les sites web \u00e0 fort contenu. Toutefois, les sites WordPress de plus petite taille b\u00e9n\u00e9ficient \u00e9galement des avantages de cette technologie. <strong>Les avantages d'un CDN sont le temps de r\u00e9ponse r\u00e9duit<\/strong>qui r\u00e9sulte de la distance r\u00e9duite entre le visiteur et le serveur.<\/p>\n<p>En outre, il y a aussi l'\u00e9conomie de trafic sur le serveur principal, puisque la majeure partie du trafic est effectu\u00e9e via le CDN et donc le grand soulagement du propre serveur ainsi que la possibilit\u00e9 de partage de charge.<\/p>\n<h2>Diff\u00e9rentes options<\/h2>\n<p>Si un CDN doit \u00eatre utilis\u00e9, il faut toujours se rappeler qu'il existe deux options diff\u00e9rentes pour l'utiliser. La premi\u00e8re option est appel\u00e9e \"Origine du client\", o\u00f9 toutes les donn\u00e9es restent sur votre propre serveur et o\u00f9 le fournisseur respectif les synchronise automatiquement avec tous ses serveurs mondiaux.<\/p>\n<p>Le grand avantage est que les donn\u00e9es ne doivent \u00eatre copi\u00e9es nulle part et qu'aucune modification ne doit \u00eatre effectu\u00e9e dans WordPress.<\/p>\n<p>La deuxi\u00e8me variante est appel\u00e9e <strong>le stockage CDN, toutes les donn\u00e9es \u00e0 livrer avec le CDN se trouvant sur le stockage du fournisseur respectif<\/strong>.<\/p>\n<p>Le stockage suppl\u00e9mentaire est g\u00e9n\u00e9ralement payant et il faut veiller \u00e0 ce que les donn\u00e9es \u00e0 livrer soient toujours transf\u00e9r\u00e9es vers le stockage du CDN. WordPress propose diff\u00e9rents plugins \u00e0 cet effet.<\/p>\n<h2>Utilisez le CDN gratuitement<\/h2>\n<p>Pour pouvoir utiliser un CDN gratuitement, Cloudflare offre certaines possibilit\u00e9s.
