When typing an Internet address, capitalization may be important.
An Internet address is only case sensitive for everything after the
domain name. For example, it does not matter if you use uppercase
or lowercase computerhope.com,
you will still reach the same page. However, when typing the name of
the page and/or directories, it is case sensitive. Therefore,
http://www.computerhope.com/jargon.htm is different than
HTTP://WWW.COMPUTERHOPE.COM/JARGON.HTM, although the domain is valid,
because index.htm is uppercase the page will not work (unless an
uppercase version of the page existed on the server). The same rule
applies if the page on the server is uppercase and not lowercase, if
this is the case than the uppercase version would work but not the
lowercase.
If you're uncertain if the page and/or directory is
uppercase or lowercase, type the address in all lowercase. The
majority of pages on the Internet are going to be in all
lowercase.
