"""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."""
