XMLHttpRequest Security errors

Hey /prog/, not a regular but I thought I'd try you guys - I'm running into problems when I try to load cross-board content using xmlhttprequest. Apparently it only works in the same domain, so I get security errors when a link pointing to img wants to load content from dat (the cross-board links send you to a redirecting page which does this). Any ideas on how to work through this? I'm running the code through the Greasemonkey Firefox extension. Thanks!

We're talking about input from the user to a web app, so yes, we are. The fact that you thought you were being clever by talking about HTML form input fields isn't particularly relevant.

(And wrong even if it were; by hashing the input to a certain form field, it becomes an encrypted field. The fact that it happens through Javascript instead of some mechanic in the HTML parser in the browser is unimportant.)
