requests module

I was exploring what the python requests module. To validate that WebLogo only downloads files from the internet, I'll use urllib2's url parser function. if the parser detects http, https, or ftp in it's scheme, then we'll lock weblogo out from accessing any local files. I'm getting valid data from the dropbox link, but I when I try to run the link through the requests.get function I get a huge blob of data that doesn't look a text file that I want to open. Dropbox sends the url for the file and presents it in a html & javascript page and puts the content in an iframe. I was trying to sort through the page to grab the data from the iframe. I'll try running the parser and try to isolate the file path, so I can grab just file instead of the entire dropbox presentation page. However, i do have the example page's lightbox module working properly again.
