You need to set the content type on the response. Try something like this:
func rewriteContentType(contentType string,handler http.Handler) http.Handler {
return http.HandlerFunc( func(wr http.ResponseWriter,req *http.Request) {
wr.Header().Set("Content-Type",contentType)
handler.ServeHTTP(wr,req)
})
}
and then:
http.Handle("/css/",
rewriteContentType("text/css".http.FileServer(http.Dir("webpages/css"))))
http.Handle("/js/",
rewriteContentType("text/javascript".http.FileServer(http.Dir("webpages/js"))))
This code probably will not compile, but it should give you the idea.
