http.Redirect不起作用

Question

i'm new to go, and i'm trying to do a redirect after login.

for the router, i'm using Mux:

router.HandleFunc("/login", pages.Login).Methods("POST")

and the Login func contains these lines:

if errorFlag {
    http.Redirect(rw, rq, "/", http.StatusNotAcceptable)
} else {
    http.Redirect(rw, rq, "/", http.StatusOK)
}

thing is, i'm getting the correct status according to the errorFlag, but the page is not redirected! the headers also seem to be set correctly ("Location:/") but instead of redirecting, the page just stays blank and remains under "/login"

i've tested it on Chrome & FF.

these are the response headers:

Content-Length:0
Content-Type:text/plain; charset=utf-8
Date:Thu, 14 Jan 2016 16:52:34 GMT
Location:localhost:8000/
Set-Cookie:user=MTQ1Mjc5MDM1N...; Path=/; Expires=Sat, 13 Feb 2016 16:52:34 UTC; Max-Age=2592000

anyone every encountered this before?

Update

As suggested below, this change works:

if errorFlag {
    http.Redirect(rw, rq, "/", http.StatusTemporaryRedirect)
} else {
    http.Redirect(rw, rq, "/", http.StatusFound)
}

thanks!

Use a 3xx status code to redirect the client (http.StatusFound, http.StatusMovedPermanently, http.StatusSeeOther, ...). The Location header is not sufficient to cause a redirect.
