title: Any good books on web site architecture (not UI design)?
body: <p>I'm developing a web site that (like many other sites) use a bunch of different tools such as php, xml, xsl, json, jquery, css etc.</p>
  
  <p>I'm looking for resources/books that can provide tips on how to use these tools more efficiently. Best practices, tips and tricks and that sort of stuff. For example how to structure files, when to use json instead of xml/xsl, ajax or no ajax and that kind of stuff. Luckily, I don't have to worry about UI design. </p>
  
  <p>Does anyone know any good books/resources that deal with this?</p>
