 """This is a blind proxy that we use to get around browser 
 restrictions that prevent the Javascript from loading pages not on the 
 same server as the Javascript.  This has several problems: it's less 
 efficient, it might break some sites, and it's a security risk because 
 people can use this proxy to browse the web and possibly do bad stuff 
 with it.  It only loads pages via http and https, but it can load any 
 content type. It supports GET and POST requests."""
