Vous avez développé votre tout dernier web service destinés à être utilisé par 2 ou 3 autres équipes en interne (voire en externe par des partenaires). Il (le web service) fonctionne bien, tellement bien, que vous commencez à avoir plusieurs dizaines de requêtes par jour. Vous n'aviez pas forcément optimisé les performances du web service, les temps de réponses ne sont pas au beau fixe car vous chargez 150 classes PHP qui sont nécessaires au tout dernier framework à la mode pour accéder à une table de base de données et faire une requête select sur un champ avec une clé primaire pour retourner la fiche descriptive d'un utilisateur, d'un partenaire ou d'un produit. Ou bien, pire encore, pour renvoyez votre catalogue de produits qui fait 150Ko une fois transformé au format XML.

Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results. Fewer downloads means a faster, happier site.

Caching is the temporary storage of frequently accessed data in higher speed media (typically SRAM or RAM) for more efficient retrieval. Web caching stores frequently used objects closer to the client through browser, proxy, or server caches. By storing "fresh" objects closer to your users, you avoid round trips to the origin server, reducing bandwidth consumption, server load, and most importantly, latency. This article shows how to configure your Apache server for more efficient caching to save bandwidth and improve performance. Caching is not just for static sites, even dynamic sites can benefit from caching. Graphics and multimedia typically don't change as frequently as (X)HTML files. Graphics that seldom change like logos, headers, and navigation can be given longer expiration times while resources that change more frequently like XHTML and XML files can be given shorter expiration times. By designing your site with caching in mind, you can target different classes of resources to give them different expiration times with only a few lines of code.

Sometimes, the price of a request when dealing with a symfony application can be overwhelming. But instead of getting back to spaghetti PHP, maybe you can get a handful of symfony features for a share of its initialization time.

This article shows 2 awesome ways to implement caching on your website using Apache .htaccess (httpd.conf) files on the Apache Web Server. Both methods are extremely simple to set up and will dramatically speed up your site!

On lit souvent sur les différentes listes de discussion sur SPIP qu’« il faut éviter de mettre du PHP dans vos squelettes ! ». La raison souvent évoquée est une question de « CACHE ». Vrai ou faux ? Soyons « THOMAS » ! Ne croyons pas sans avoir vu…

This document describes reverse proxies, and how they are used to improve Web server performance. Section 1 gives an introduction to reverse proxies, describing what they are and what they are used for. Section 2 compares reverse proxy caches with standard and transparent proxy caches, explaining the different functionality each provides. Section 3 illustrates how the reverse proxy actually caches the content and delivers it to the client. Section 4 describes how to configure Squid as a reverse proxy cache.
