Since you are talking about a management tool via http, you might consider
using a second server process for this. If you select the 'restart link'
then under water you need to (a) startup a server on a different port,
(b) redirect to a URI on that server, (c) make it that that URI restarts
the main server as you would normally do, (d) clean up the second server
as soon as the main server restarts.
You can do this in a sophisticated manner by creating a httpd config on
the fly, using a unique restart-URI, thus avoiding the most obvious 
security risks.

Might work...
