Betsy:

Research redirects for redirecting various URI to a specified URI.

The modrewite módule for Apache will provide a richer method to handle various URI/URLs. One can rewrite ‘thirdtimesthecharm’ to ’3rdtimesthecharm’ using a regular expression, ‘*timesthecharm’ (research regular expressions; my syntax “*…” is simplified).

Webserver rediects are simpler to setup but do not handle regular expression without a module.

Great post – I do have a question though, if I have a Facebook page that has a URL with “3rdtimesthecharm”, but people might instead write “thirdtimesthecharm” in the URL…can I have multiple URLs for people to type in and have them both direct to my page?

Thanks so much!

Thanks for the informative and well written article Igor. I love the way you outline the steps clearly and connected the dots, even having those side notes in boxes. Definitely useful for beginners and for experienced developers like me who need a refresher once in a while

Great post. Just what i need to create the power point presentation for my students. thanx. btw when different domains point to the same IP then it is the web servers responsibility to present the correct domain files to the browser.

2 Shouvik:

The author actually meant IP addressess are different, but DNS lookup returns the only IP for each of these domains. As you can see from the article, the returned IP can be different in some cases depending on load balancing, geo IP, etc.

Nevertheless, there’s tons of situations when a number of domains resolved to the single IP, and that’s no problem for DNS, as forward DNS lookup is resolving a domain name to an IP address. Ambiguity will arise in the case of reverse DNS lookup, when IP address is resolved to a domain name. However it’s outside of this article topic, as a web browser performs only forward lookups.

Web server can handle multiple domains with no problem basing on request sent by a browser (see Host field of the request).

Nice article. very informative. I would have loved if you had written a bit about the roles of TCP and IP in the protocol stack.
