Web.go如何进行http重定向？

Question

I am writing a small app using web.go with a function that serves a form. If the form is not valid, user will be redirected to the same page:

func mypage(ctx *web.Context) {
     if ctx.Request.Method == "GET" {
         // show the form
     } else if ctx.Request.Method == "POST" {
        // redirection if the form is not valid:
        ctx.Request.Method = "GET"
        http.Redirect(ctx.ResponseWriter, 
                      ctx.Request, "/mypage", http.StatusNotAcceptable)
        return
     }
}

This works, with one caveat that when the form is not valid, it first shows a page with the text "Not Acceptable" that is liked to /mypage. How can I make it to go directly to /mypage in case the form is not valid? I suspect that it is related to http.StatusNotAcceptable but I don't know what I should replace it with.

So turns out it was easy :)

ctx.Request.Method = "GET"
mypage(ctx)

No need for http.Redirect. The important part is to change the Method to GET first, before calling mypage(ctx).
