Yes, but in most (all?) implementations OpenLayers is loaded only once 
into your browser.  It then makes requests to mapserver for data (i.e an 
image on every pan and zoom).  In the "old" way (without OpenLayers or 
some similar JavaScript/Java package) of configuring mapserver, 
mapserver would deliver HTML, images, etc to render the entire interface 
on every pan and zoom.  I don't think many people use it this way 
anymore since browsers are a lot more capable, but you can configure it 
this way if you really want to.

   Have a look at the OpenLayers examples.  Use your browser's debugging 
tool to see the conversation between OpenLayers and mapserver.

Note to Mapserver documenters: we need to update the Mapserver 
Introduction (especially the "Anatomy...") to show the more modern AJAX 
style implementation.
