How to add a IHttpHandler in runtime

[Bas]

Hi all,

here's what I'm trying to do:

I made a class library in .net 2.0 beta2 that contains a webcontrol. When
this webcontrol is used, I want to add a custom IHttpHandler for a certain
request path, let's say "MyControl.xmlx", in order to allow the webcontrol to
do client side XML data requests.
I tried adding the handler to the WebConfiguration for
'web.config/httpHandlers' in the Load event of the control. However I suspect
this change is discarded as soon as the load event handler goes out of scope.
Also, calling Save on the configuration is not an option since the handler
should not persist outside of the lifespan of the current Application object.
That and the web.config is read only in almost all cases.
To make a long story short, it all boils down to this one question: how can
I tell the current web Application to use my HttpHandler without using the
web.config file?

Is this even possible?
