Terminating a connection in mod_proxy

[Peter Belau]

Hi,

I'm trying to figure out how I would send data back trough mod_proxy based on a 
certain request. For instance: upon seeing a GET to www.google.com, I'd like to 
return "Hello world" *without* the request ever getting to www.google.com. 
Would anyone know how to do this ?

Thanks,

Peter
