Difference between html,shtml,htm

  1. Jun 30, 2004 #1
    What are the differences between them ?
    Another question, sometimes I see some internet addresses like http://FalseWebpage.com/ [Broken]
    why isn't there www before FalseWebpage ?

    Thank you,

    html = hyper text markup language
    shtml - html that is using sever side includes
    htm = abbrivation for html

    DNS (domain name system) works by translating a URL/domain name to an IP address.... There is no need to put a www in front if the domain point to the web service rather than lets say the SMTP service that this domain is hosting....

    Your question cant be answered in a short post... Sorry to say this but you should RTFM on this one :-) I would suggest you read some RFC's for example RFC 1034 which describes DNS... If you have a grasp on DNS then you will understand why you do not need to put www in front

    www is actually just a folder on the web server, information inside needs the www, information outside doesn't. It's just become a standard overtime to include a www folder as a formality.

    actually www is the bottom level in the DNS name (Domain Name) .com being the top... a folder would come after the .com for example


    A web server could just as easily sit at


    As long as you have a DNS zone per level specified on your name server you can go as far as you want...
