inject code into masterpage / html head from a user control
<p>I am struggling with something that I guess should be standard practice really.  I have a number of user controls that use some JQuery plugins.  I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control.  Then I looked at my source HTML, not nice!  Even worse for controls that repeat multiple times on a page.</p>

<p>So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control.  For that matter is there a way of doing it to the footer for JS stuff?</p>
