ASP.NET Permanent Redirect (301)

ixnay2infinity (AvG) — Thu, 24 Jul 2008 01:36:54 GMT

Response.Redirect normally returns a 302 Object moved HTTP response. However a 301 permanent redirect is often better for search engine spiders:



Response.StatusCode = 301;

Response.AddHeader("Location", "New.aspx");

Response.Write("Page moved permanently to New");

Response.End();

Redirect a URL with Ruby CGI

jrobertson (James Robertson) — Mon, 21 Apr 2008 12:25:30 GMT



#!/usr/bin/ruby



require 'cgi'



cgi = CGI.new

print cgi.header({'Status' => '302 Moved', 'location' =>  'http://www.wired.com'})



url = 'http://www.wired.com/'

print cgi.header({'status'=>'REDIRECT', 'Location'=>url})

Rails: 301 Permanent Redirect

MattScilipoti (Matt Scilipoti) — Fri, 16 Nov 2007 06:17:21 GMT

First there was:



 headers["Status"] = "301 Moved Permanently"  

 redirect_to "http://www.newdomain.com"

Then there was:



head :moved_permanently, :location => book_url(@book)

As of [7820] on 2007/10/09, there's a new redirector in town.



  # Examples: 

  #   redirect_to post_url(@post), :status=>:found 

  #   redirect_to :action=>'atom', :status=>:moved_permanently 

  #   redirect_to post_url(@post), :status=>301 

  #   redirect_to :action=>'atom', :status=>302

sweet.

I know this is a lame snippet, but I'm tired of writing this from scratch every time.

Java Script Redirect

Alternately, something like..

Click here

which stops it from being indexed (although rel="noindex" does the same on some engines).

Performing a redirect with AJAX

brianellin (Brian Ellin) — Sat, 14 Jan 2006 02:55:30 GMT

If a redirect is returned from the rails' form_remote_tag or link_to_remote methods, a message is displayed saying something like "You are being redirected", where "redirected" is a link the user must click. The code snippet below will actually redirect the user to the proper location, without them having to click the link. Code works for both form_remote_tag or link_to_remote methods.



<% link_to_remote "Foo",

                  :url => { :action => "foo" },

                  302 => "document.location = request.getResponseHeader('location')" %>

Or, an example from the Typo source:



<%= form_remote_tag :url => {:action => "comment", :id => @article}, 

                    :update => {:success => 'commentList'},

                    :loading => "loading()", 

                    :complete => "complete(request)",

                    :failure => "failure(request)",

                    :html => {:id=>"commentform",:class=>"commentform"},

	            302 => "document.location=request.getResponseHeader('location')"%>

Redirect back to a previous action

pmark (P. Mark Anderson) — Wed, 04 Jan 2006 18:08:12 GMT

I am pasting this verbatim from LoginSystem



# move to the last store_location call or to the passed default one

  def redirect_back_or_default(default)

    if @session[:return_to].nil?

      redirect_to default

    else

      redirect_to_url @session[:return_to]

      @session[:return_to] = nil

    end

  end

In your controller...



 redirect_back_or_default :controller => "myfuel", :action => "index"
