Search Engine Friendly Redirects

It is quite common to lose out on a lot of valuable search engine traffic due to incorrectly configured redirects.

It is very import that when a search engine comes to crawl your website it is able to follow any redirects you have set up.

Suppose you have a website http://www.foo.com and you create a redirect such that whenever any visitor types in the URL http://www.a1.com he is automatically redirected to http://www.a1.com/widgets/, If the Search Engine is not able to follow the redirect it would think that http://www.a1.com has NO contents, http://www.a1.com would end up ranking very badly in search engines.
