"""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."""
