+"""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.  If you can get your code signed (see:
+http://trac.openlayers.org/wiki/HowToSignJavascript), then you should
+modify Parameters.js so that this isn't used.  Otherwise, you're stuck
+with it.  It only loads pages via http and https, but it can load any
+content type. XML and HTML are both currently used by Openlayers."""
