Get entire page including dynamic elements with cfhttp?

I'm trying to read a page with cfhttp and extract code from it using #find. I've done this before and it works fine. The problem is that the page I'm trying to read has lots of embedded AJAX mechanisms — when I use my browser's "inspect" function on particular attributes I can see all the code, but when I simply say "show page code" (or use cfhttp) I just get the top-level static code without the sub-components that load when the page loads (the code of which are visible when I select elements and click "inspect" using the browser's debug tools).

Is there a way to tell coldfusion to read from a specific http location and load the entire file, the way a browser does, rather than just retrieving the top-level file and ignoring the javascript and other mechanisms that fill the page dynamically with code as it loads?

Thanks in advance for anyone's help or advice.
