cross site scripting
<p>Can I call a URL from a different host and write a variable to it without running into XSS security issues? This is what i am trying to do-</p>

<p>Send usernames + load a url in iframes from my site to a different site. I am doing this in javascript. I am actually able to do this but I am reading that browsers should be blocking it and its possibly a security concern? </p>
