"chaining the calls to append() in your jquery" What is it, what is the risk of not doing it?
<p>The comments section of this article: <a href="http://ayende.com/Blog/archive/2010/09/18/resolving-cross-site-scripting-issues.aspx" rel="nofollow">http://ayende.com/Blog/archive/2010/09/18/resolving-cross-site-scripting-issues.aspx</a> has a very interesting comment.</p>

<p>In it, Mark mentions that I need to jain the calls to append to prevent "$(childDiv) lookup multiple times".  </p>

<p>What is the impact of the vulnerability of "$(childDiv) lookup multiple times"?</p>
