There are many possible ways to implement redirects. On Apache web servers (normally present on machines running Unix or Linux as the operating system), it is possible to implement redirects quite simply in a standard file called .htaccess using the Redirect and RedirectMatch directives (learn more about this file format at http://httpd.apache.org/docs/2.2/howto/htaccess.html). More advanced directives known as rewrite rules can be employed as well using the Apache module known as mod_rewrite, which we will discuss in a moment.
On web servers running Microsoft IIS (http://www.iis.net/), different methods are provided for implementing redirects. The basic method for doing these redirects is through the IIS console (you can read more about this at http://www.mcanerin.com/EN/articles/301-redirect-IIS.asp). People with IIS servers can also make use of a text file with directives provided they use an ISAPI plug-in such as ISAPI_Rewrite (http://www.isapirewrite.com/), and this scripting language offers similar capabilities as that of Apache’s mod_rewrite module.
Another method that you can use to implement a redirect occurs at the page level, via the meta refresh tag, which looks something like this:
<meta http-equiv=”refresh” content=”5;url=http://www.yourdomain.com/newlocation.htm” />
The first parameter in the content section in the preceding statement, the number 5, indicates the number of seconds the web server should wait before redirecting the user to the indicated page. This gets used in scenarios where the publisher wants to display a page letting the user know that he is going to get redirected to a different page than the one he requested.
The problem is that most meta refreshes are treated as though they are a 302 redirect. The sole exception to this is if you specify a redirect delay of 0 seconds. You will have to give up your helpful page telling the user that you are moving him, but the search engines appear to treat this as though it were a 301 redirect (to be safe, the best practice is simply to use a 301 redirect if at all possible).
