Protecting your site from hotlinks can be really useful to prevent other sites stealing bandwidth, but it's also comes handy when you want to protect files from private areas. The first 2 lines are responsible from redirecting all the traffic from www.yoursite.com to yoursite.com and the third and fourth line is for preventing hotlinks, in this case PDFs and SVGs.

In a way to build an entire layout for a web application we need to know what exactly we need. In this case I'm going to use a 90% width with a top menu, left menu and a right handed help box used to explain what the current section does. It's always useful to draw a mockup of the layout we want to achieve. Since this is a kind of simple layout we don't really need it, but I still did it.

When developing web aplications I usually need to put all the menu in a tree-like organization.
