[PATCH]: Multiple Tomcat 3.2 ISAPI redirectors on the one machine

[Tim Whittington <Ti...@orion.co.nz>]

Afternoon Larry & Ignacio,

I've updated the patch to use a .properties file and
to remove the dependency on shlwapi.dll (uses _splitpath/_makepath instead).
I also added a flag to indicate in the log what settings (properties or
registry) 
were being used.
Also brought the code style into line with the rest of the file (sorry).
The patch is now against the 1.6 revision in CVS (previously from the 3.2.3
distro)

It was a mission to create a minimal diff for this as the files in CVS have
a 
mix of DOS and Unix LFs. Had to do a manual merge to stop the editor
converting the LFs.

regards

tim
