You can set a <WatchedResource> tag inside the <Context> element for
your webapp; changing the target of that should trigger a reload of the
app.  Look here for doc:

Should be able to do it by sending a delayed refresh of the console page
back to the client, and also forwarding a request to the html-manager
app to do the redeploy.  A bit of a kludge, but it can probably be made
to work.  Shouldn't be needed with <WatchedResource>.

But better just to process the updated .ini file without redeploying the
app, if possible.
