Ultimately, there comes a point in almost every application’s life where it needs to either protect resources, or access protected resources.

Supporting Multiple Browsers in Web Applications

Around this time last year, I was developing a website for my wedding. The primary function of this website was to have guests RSVP on the site, so we could save a little money on postage and letterhead.

Before you ask, no I don’t know why the conference is named ConFoo, but I can tell you what ConFoo is. The Confoo Conference is an international conference focusing on various aspects of web development. It began as a conference focusing strictly on PHP programming, but in the 15 years since its conception Yann Larrivée, the conference’s founder, has grown it into a developer-focused colloquium focusing on multiple technologies, the majority being used within a web-development context.
