Include a small picture of 1x1 transparent pixel somewhere unnoticable:

  <div class="footer">
    adlkasdlk asda sd (c) 8123932
    <img src="blank.png" width="1" height="1" id="actionimg" />

Then from javascript - change the url of "actionimg" to
"/?my_request.py/method?askdjasdlkjakjsd". You won't be able to receive
anything useful though, so this could be used to change some internal
server state.

You COULD return some other picture and use that as some information
flow to the user. For instance, you could change the color of some image
according to the internal web server state - by just changing to some
method that returns the other image.
