What is the difference b/w http://www.something.com and http://something.com
-
www. ? ;P Me think that the browser will add the missing elements or the URL when it's trying to resolve the address; or maybe do a quick search and return the first find. for example, in firefox, if you type codeproject, it will take you here.

www. is a subdomain of something.com I still don't get why everyone started using www.something.com anyway. To help the ignorant public remember websites?

Not a full answer as I don't know all the technical terms but... The
httppart is the protocol. For instanceftp://something.comwould communicate with that domain using the ftp protocol.httpsis an http protocol connection but secured using SSL (normally). There are many other protocols but those are the three major ones.something.comis the full domain name. TheCOMpart is theTLD(top level domain e.g.co.uk,co.za,net,orgetc.) This is registered with a domain name provider and mapped to some nameserver. [Edit] Anders pointed out that I was incorrect about the term alias, it is in fact a sub-domain. So in the following think sub-domain and not alias. I think this also changes the "setup on the server" bit.[/Edit] Thewwwofwww.something.comis as far as I remember called an alias. It is setup on the server that the domain points to. You can have as many aliases as you wish, or none at all. In this case www stands for world wide web and has just become some kind of agreed on standard. It is not neccesary but it is a good idea to have. For instance some servers will, confusingly, have the following:http://ftp.something.comwhich is like a ftp connection but over the http protocol. Useful but confusing. I don't know if there is a limit but you can string aliases together e.g.http://subalias1.subalias2.subalias3.something.comis valid. Depending on your server software you can have aliases pointing to different folders/directories on your server. Or they can all point to the same one or a mixture. e.g.http://www.something.comandhttp://something.comwill generally point to the same place as many of us like to skip the www bit (for me, servers that balk at skipping the www bit are a PITA).

Unfortuanately this is not true. The server has to be setup to handle alias-less URLs. The Code Project servers have been setup to handle an URL without the www bit gracefully. It has to be setup with IIS though, it is not default behavouir. The browser idea is nice but it might cause other unintended problems, who knows. regards, Paul Watson South Africa The Code Project South-East Asia Disaster: How you can help Pope Pius II said "The only prescription is more cowbell.

Anders Molin wrote: www.codeproject.com is not an alias for codeproject.com, it's a subdomain. I'm sorry, but this again is not entirely true. In fact it is ambiguous. It could be a subdomain of codeproject.com but more likely www is the actual hostname or one of the hostnames as you can create multiple A records for one address (see Domain Name System: 2.2 Understanding the parts of a domain name[^]).

www. is a subdomain of something.com I still don't get why everyone started using www.something.com anyway. To help the ignorant public remember websites?

I still don't get why everyone started using www.something.com anyway. To help the ignorant public remember websites? The Internet and its addresses predate the web. In "the old days" there would frequently be several independant addresses within a domain that you might be interested in. We might have the ftp server be at ftp.something.com, the gopher server at gopher.something.com, the e-mail server at mail.something.com, and so on. Then there would be any number of individual workstations, probably called frodo.something.com, samwise.something.com, pippin.something.com, etc. (I believe there was an RFC stating that all workstations MUST be named after Lord of the Rings places and characters, preferably hobbits). When the web came along, it was just another service that was to be added to a domain, so www.something.com was born. Now a domain's main function is usually to be a webserver, so the www is redundant. It bugs me when one works but not the other.

I'd say what you just wrote is pretty much up-to-date. Most "real" networks (I'm not talking about shared web hosts at some ISP) still have those ftp.something.tld, mail.something.tld and so on A records (and of course the associated hosts). Often there are even A records for the real hostnames of the machines.

The browser (including IE and Mozilla/Firefox) will add both "www." and ".com" (this can usually be changed through the UI or registry hacks) when neither is present, but not one or the other. This is, of course, default behavior. Plugins/extensions may change such default behavior. This posting is provided "AS IS" with no warranties, and confers no rights.

Actually, "www" is usually a host not a sub-domain. I suppose that some sites' DNS configurations may make it a sub-domain vs. an A or CNAME record, but it is usually a host.
