www. vs http://

[watts3000]

Can someone tell me the difference between websites that use www and http

http:// stand for hyper text transfer protocal. It basically defines the protocol you want to use to transfer data. Http: is generally associated with TCP port 80.

Other protocls include https which is http secure
ftp or file transfer protocol and i believe one that is basically never used called gopher.

WWW on the other hand has nothing to do with protocols. It stands for world wide web and is part of the address.

however not all addresses have www.

so to recap.

HTTP:// defines a protocal while www is part of the adress.

Think of it as this. When you send a letter the WWW is part of the mailing address and the HTTP:// could be representative for airmail. FTP could be express and HTTPS could be considered registered mail.

EDIT just to be complete.

FTP is generally associated with TCP port 21 and HTTPS is generally associated with TCP port 443

http is an internet protocol that allows you to view web pages

www is used to be a host name (a common server name). An internet address does not need to have www. It can be sales.internet.com and doesn't have a www in front of it. However, people around the world are used to www in front of their domain name and it is still being widely used.

Most websites are not actually called "www".whatever.com, but rather use an alias (CNAME) via DNS records. The webserver may be called whatever.com, but an alias exists that directs you to whatever.com when you type in www.whatever.com.

Look in the OS forum for your cross post to get the same answer (basically) you got here. And please stop cross posting 🙂

not trying to be a smart a** but is there some type of rule that says you can't cross post

<< is there some type of rule that says you can't cross post >>



Im not positive its a rule, but it is part of the netiquette FAQs all ove the web.

Depends on the site. Some sites automatically put in www for you even if you don't. Some sites are not using "www" and won't work if you do use it, some do work if you do. It all varies from site to site, but you shouldn't get a headache over it..

Sites that setup their dns servers to require the www. are annoying.
