Funny thing about URL's

Recently after years of web-programming I noticed a subtle thing.
Whenever we make a request for a website, say http://narencoolgeek.blogspot.com, the URL in the browser changes to http://narencoolgeek.blogspot.com/ . (Notice the forward slash at the end of the URL)

I put in a sniffer to see what is exactly happening. The server on receiving the first URL sends a 301/302 (temporary moved) response redirecting the client to the new URL. Why is this necessary? Maybe some legacy reason, or maybe this is necessary to pick up the default page of the website directory.
