I've been coding desktop client/server apps for a few years (telnet as the protocol). I've built basic websites in the past. Now I'm in an environment where I work exclusively with rich web applications.<p>What's my best bet for getting up to speed? Should I learn about web servers and HTTP in depth, focus mainly on the platform I'm using (asp.net/iis), or some other approach?<p>Thanks!
JavaScript, CSS, HTML and REST is what you should learn everything else is transferable to any back end language and servers you choose.<p>Once you start building applications in this manner you can write you REST services in the language of the day and implement it on the server of the day.
