Erik,

basically, I think what matters most is whether the request method is  
defined for the geo: protocol.

I do not think that http forbids the use of non http URIs because the  
client component is supposed to select the correct connector based on  
the protocol. So, a geo: URI would normally never end up in an HTTP  
request.

OTH, HTTP 1.1 requires the Host header field and if that does not  
match the host of the URI you end up with a proxy request anyway. So  
the question would technically be how the target host of the first  
request hop (as given in the Host header) deals with the geo: URI. If  
you write a proxy to do some sort of resolution of the geo: URI I  
think that should work.

HTH,

Jan
