Hi guys! I was wondering how i would go about making a framework for a flash site.
The site im working on now has a main framework swf, which loads in external swf and treats them as pages in a site. The swf does background loading and simply puts the loaded swf when the user clicks on the appropriate navigation button.

But what im curious about is sites such as this one, how do they make it that the links within the flash changes the URL on my browser and i have forward and back capabilities?

And also, im currently having problems passing variables from the external loaded swf into the main framework. Im getting error 2047, which is a security sandbox violation error. I need this so that the external swf for example can tell the main swf to go and show another pager when a user clicks on a button inside the external swf. How do i go about doing this?

As of now im only familiar with AS3 and FlashDevelop. I have almost zero knowledge on any other languages. Is it possible to create something like that with what i know right now? If so it'd be great if you guys can give me some pointers how i can go about doing that.

thanks!
