Hi,

What you can do is restart individual mod-mono-server.exe processes 
using the mod_mono control panel.  See: http://mono-project.com/Mod_mono 
   (I don't think the control panel was in the version mentioned by the 
previous poster on this thread.)  That'll let you reload testing 
environments without affecting the production application, for instance.

To do that, you'll need to make sure you split your production and 
testing environments into two so-called applications in separate 
mod-mono-servers by using separate AddMonoApplications directives with 
different aliases (see the section  Two Applications, Two mod-mono-servers).

If additionally the AddMonoApplications directives are within separate 
VirtualHost sections, at least in Apache 2, the mod_mono control panel 
for each virtual host will restart just the corresponding 
mod-mono-server.  Otherwise, there's no way to restart just one.  (I 
posted a patch that fixes that and does other things a few days ago -- 
I'll try to commit just this portion of the patch soon so you can always 
restart mod-mono-servers selectively.)

Hope that helps.
