I think you'll have to check the http.Request.Host and conditionally execute
the ServeHTTP method of an http.FileServer based on it.
You can find an example of what I'm describing below. I hope I understood your
problem.
package main
import (
"log"
"net/http"
)
func main() {
webrootdomain1 := "./assets1"
webrootdomain2 := "./assets2"
http.HandleFunc("/assets/", func() func(http.ResponseWriter, *http.Request) {
// create a closure with our file handlers.
fs1 := http.StripPrefix("/assets",
http.FileServer(http.Dir(webrootdomain1)))
fs2 := http.StripPrefix("/assets",
http.FileServer(http.Dir(webrootdomain2)))
// retrun a function that executes the ServeHTTP() method of
one of our
// filehandlers based on the contents of r.Host.
return func(w http.ResponseWriter, r *http.Request) {
log.Printf("got request for host %q, path %q", r.Host, r.URL.Path)
switch r.Host {
case "localhost:8080":
log.Printf("trying to serve file for domain %q", r.Host)
fs1.ServeHTTP(w, r)
case "anotherdomain.com":
fs2.ServeHTTP(w, r)
}
}
}())
http.ListenAndServe(":8080", nil)
}
