Duplicate Content URLs, HTTP, and WWW

[Terrence Taitt]

I would like to know where on my hosting account could I find the .htaccess file. Also, what is the difference between these two URLS related to the issue of duplicate content and also what is the purpose of the http in the url:

http://www.makemoneyonlinesite.net


http://makemoneyonlinesite.net

Which one of these domain names should I use, when building links to my websites' home page, as well as to deeper web pages?

You should pick one and stick to it because they count as different pages.

The .htaccess belongs in the same folder as your index.html or your root direectory.

If, I am building links to the home page of my website, and I set http://www.mysitename.com to be the URL to which page rank will flow, what will be an instance where duplication can occur (i.e., in the domain name structures)? For example, If I enter www.mysitename.com into the browser or mysitename.com. Please explain when URL duplication could possible occur, and how do I fix this problem.

If you have questions you can follow the examples below:
Sample Rules

To redirect an old domain to a new domain:
RewriteCond %{HTTP_HOST} old_domain\.com [NC]
RewriteRule ^(.*)$ http://www.new_domain.com/$1 [L,R=301]

To redirect all requests missing "www" (yes www):
RewriteCond %{HTTP_HOST} ^domain\.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]

To redirect all requests with "www" (no www):
RewriteCond %{HTTP_HOST} ^www\.domain\.com [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [L,R=301]
