How to redirect using JavaScript, ColdFusion, PHP, ASP, ASP.net. JSP, PERL, Ruby, HTML or .htaccess?

Using a redirect allows a website owner to direct a website visitor from one webpage or website to another.  There are two popular ways to redirect a website visitor/search engine, "302 redirect" and "301 redirect".  The method of redirection is basically the same code-wise but on the server-side or search engine optimization view point they are completely different.

The examples below are small snippets of code using the 302 redirection method.  The method called a "302 redirect"; the 302 code is a HTTP status code which is interpreted as a "temporary move".  Below you will find how to code a 302 redirect using popular scripting languages.  Depending on your objective you may want to use the 301 redirection method.  The method is called a "301 redirect"; the 301 code is a HTTP status code which is interpreted as a "permanently moved".  The 301 redirect is a preferred method if you want to preserve your search engine ranking.

302 Redirection using ColdFusion

The following ColdFusion code must be run on a server which can interpret ColdFusion coding - such servers include Microsoft IIS (Internet Information Server) with ColdFusion support.  Like all server-side languages, the server needs to interpret the ColdFusion code before rendering it.  When the server gets to line 1 below it will redirect the page immediately.  If there are other elements on the page such as text, graphics, video, etc. they will all be ignored.

ColdFusion

Perl (Practical Extraction and Report Language) or CGI (Common Gateway Interface)
