Server2Go is a Webserver that runs out of the box without any installation and on write protected media. This means that web applications based on Server2Go can be used directly from cdrom, a usb stick or from any folder on a hard disk without the hassle of configuring Apache, PHP or MySQL. Server2Go allows you to create a standalone working web site or PHP application on a CD-ROM. There are many examples of its possible useses such as catalogue software, calculation programmes, image campaigns (CMS-based), computer based training lessons or other applicatons. Most PHP-Software such as the content management system Joomla or the computer based training software Moodle can be used from CD-ROM with the help of Server2Go. Server2Go was developed in the first instance for use on CD-ROM but there is no problem in using it from other drives too. Using a web browser, a user can run php programs as well as view html files on the CD-ROM. He only needs to insert a CD with Server2Go. The server software starts automatically and a browser is opened with the Website of the CD-ROM. Server2Go was built in the first place to replace other CD-ROM webservers such as WampOnCD or Microweb that lacked some important features or are not being actively developed. Main Features * Free! No royalties * Complete WAMPP Server-Stack * Runs directly from CD-ROM, USB Stick or Hard disk without installation * Full featured webserver (based on apache) * PHP 5.x support with many extensions installed (e.g. gd) * Supports SQLite databases * Runs on all versions of Windows from Win 98 and above, MAC OSX support is coming * Support for MySQL 5 Databases * Supports many PHP extensions (GD-Lib, PDO...) by default * Support for Perl 5.8

OpenID is another one of those "cool technologies you've never heard of" type of deals. OpenID is an open source initiative that provides a way for Web users to register their identity in one place and then use that identity anywhere on the Web that supports OpenID. This means that, as a user, you don't have to keep creating (and remembering) new user names and passwords at every site you visit. And, as a service provider, you can identify and authenticate users that show up at your site without having to do all of the user management involved in giving them access. The list of services that support OpenID is growing, but not as fast as it should be given how cool and useful OpenID is. Hopefully, this article will help with that. The idea behind OpenID is fairly simple: a Web user can get an ID from an OpenID provider and use that ID to access any Web application or service that supports OpenID.

This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Etch. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.). From the HAProxy web site: "HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware. Its mode of operation makes its integration into existing architectures very easy and riskless, while still offering the possibility not to expose fragile web servers to the Net."

Les problèmes de montée en charge sont choses courantes pour un site ou une application web une fois atteint un certain succès. Ces derniers sont bien trop souvent négligés, généralement jusqu’au jour où se trouve atteinte la limite critique entre l’inconfort et l’instabilité. Le trend actuel veut qu’il soit à la fois plus simple et moins cher de rajouter des machines que de reprendre son code en profondeur pour l’optimiser. Encore faut-il que l’application permette un redimensionnement de ce genre sans rentrer dans une phase de refactoring complet. Évidemment, avant d’en arriver à une solution aussi lourde, il vaut mieux s’assurer que tout a été fait pour exploiter au mieux les ressources disponibles, et cela passe notamment par un peu d’optimisation côté serveur.

Le sujet était "Déboguer une application web avec FirePHP". Déboguer une application web peut rapidement devenir fastidieux. L'utilisation d'un débogueur simplifie ce processus mais il n'est pas toujours possible d'en utiliser un. FirePHP est une extension Firefox qui permet de fournir des informations de déboguage sans interférer avec l'affichage de l'application web. Cela est particulièrement pratique pour déboguer de l'Ajax par exemple.

This article explains how to set up a two-node load balancer in an active/passive configuration with Pound and keepalived on Debian Etch. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server.

Applications using the LAMP (Linux®, Apache, MySQL, PHP/Perl) architecture are constantly being developed and deployed. But often the server administrator has little control over the application itself because it's written by someone else. This series of three articles discusses many of the server configuration items that can make or break an application's performance. This second article focuses on steps you can take to optimize Apache and PHP. Linux, Apache, MySQL, and PHP (or Perl) form the basis of the LAMP architecture for Web applications. Many open source packages based on LAMP components are available to solve a variety of problems. As the load on an application increases, the bottlenecks in the underlying infrastructure become more apparent in the form of slow response to user requests. The previous article showed you how to tune the Linux system and covered the basics of LAMP and performance measurement. This article focuses on the Web server components, Apache and PHP.

Sahi is an automation and testing tool for web applications, with the facility to record and playback scripts. Developed in java and javascript, this tool uses simple javascript to execute events on the browser. Features include, in-browser controls, text based scripts, ant support for playback of suites of tests, and multi threaded playback. It supports HTTP and HTTPS. Sahi runs as a proxy server and the browser needs to use the sahi server as its proxy. Sahi then injects javascript so that it can access elements in the webpage. This makes the tool independent of the website/ web application.
