Hi Arnie,

You probably want to look at pgRouting for the server side application. 
I wrote my own extension to this that generates driving directions. You 
can see it here:

The actual driving directions extension is specific to the data I'm 
using, but I have discussed how it is done on the pgRouting list.

I have a vague recollection that someone might have written a Dijkstra 
solver that runs in JavaScript that could be applied to small networks, 
but I think you need to look at server side solution for more general 
applicability.

You can look at the link source to see how I integrate the Ajax requests 
with OpenLayers.

Hope this helps,
