+The same server, running as a Spiffy vhost request handler:

+(use spiffy xml-rpc)
+
+(define (say-hello var)
+  (sprintf "Hello, ~A!" var) )

+(vhost-map

+
+(start-server)

+
+When requesting any resource under the host {{test1}}, this will
+trigger the XML-RPC handler.

+(require-extension xml-rpc-client)

+(define srv1 (xml-rpc-server "http://test1:8080/RPC2"))
+(define hello1 (srv "hello"))

+(define srv2 (xml-rpc-server "http://localhost:8080/RPC2"))
+(define hello2 (srv "hello"))
+
+
+;; Prints:
+;; -> Hello, you!
+(print "-> " (hello1 "you"))
+
+;; Throws an (exn http client-error), with 404 not found:
+(print "-> " (hello2 "you"))
+</enscript>
+
+If you wish more control over exactly under which URIs the XML
+resource is available, you could have a look at [[uri-dispatch]], or
+roll your own URI path checker.
