How can I trigger a get from javascript
<p>Sorry about the relatively vague title, I can't think of anything better.</p>

<p>Anyway, so I have a page that shows a camera feed and I want to control pan/tilt. I've a python cgi that controls the actual nuts and bolts of that and spits out the html, the image being updated by javascript, and is looking for ?action=(left|right|up|down). I'm trapping key presses for that bit, but I can't figure out how to trigger a GET to the cgi without reloading the whole page. Is there any way I can do this or will I just have to reload the page? </p>

<p>Thanks</p>
