Adios Means Goodbye – Browser 301 Redirects In All Languages

Browser redirects, especially 301 "permanent" redirects, are essential to all good web applications. Regardless of language, browser redirects can:

• provide safe URL forwarding to gather GET and POST variables and process them without risking data and processing integrity by a browser refresh
• send users and search engine bots to the new location of a page or entire website
• maintain search engine rank and avoid 404 errors

Here's the list of browser redirects using various languages:

.htaccess

redirect 301 / http://www.davidwalsh.name/

ASP

Response.Status="301 Moved Permanently";
Response.AddHeader("Location","http://www.davidwalsh.name/");

ASP.NET

ColdFusion

<CFHEADER statuscode="301" statustext="Moved Permanently">
<CFHEADERname="Location" value="http://www.davidwalsh.name">

Javascript (NOT a 301)

//window.location.href = 'http://www.davidwalsh.name/';

Java JSP

response.setStatus(301);
response.setHeader("Location", "http://www.davidwalsh.name/");
response.setHeader("Connection", "close");

Meta tag (NOT a 301)

<meta http-equiv="refresh" content="0;url=http://www.davidwalsh.name/" />

print "Status: 301 Moved Permanantlyn";
