How to fix a canonical problem with no htaccess?

[bronxpad]

Basically I need to find a way to fix my canonical problem. The www and no-www version of my site each show up. This creates duplicate content. I have no htaccess with yahoo. How else can I fix this problem? Does anyone have a sample code I could use?

In your Google webmaster account add and verify both the domain http://example.com and http://www.example.com

Suppose you want to set www version as preferred method then in the Configuration >> Settings of both the domains under webmaster tool set www version as preferred

Also, you can add the canonical tag under the head section of each page as follows:

<link rel=<a class="attribute-value">canonical</a> href="[http://www.example.com/actual-page-name-comes-here.html](view-source:http://www.snapdeal.com/deals-delhi)"/>

Ok, so I don't need a 301 redirect?
