POCloudfront Custom Origin Is Causing Duplicate Content Issues
text
Body
copied!<p>I am using CloudFront to serve images, css and js files for my website using the custom origin option with subdomains CNAMEd to my account. It works pretty well. </p> <p>Main site: www.mainsite.com</p> <ol> <li>static1.mainsite.com</li> <li>static2.mainsite.com</li> </ol> <p>Sample page: www.mainsite.com/summary/page1.htm</p> <p>This page calls an image from static1.mainsite.com/images/image1.jpg</p> <p>If Cloudfront has not already cached the image, it gets the image from www.mainsite.htm/images/image1.jpg</p> <p>This all works fine.</p> <p>The problem is that google alert has reported the page as being found at both:</p> <ul> <li><a href="http://www.mainsite.com/summary/page1.htm">http://www.mainsite.com/summary/page1.htm</a></li> <li><a href="http://static1.mainsite.com/summary/page1.htm">http://static1.mainsite.com/summary/page1.htm</a></li> </ul> <p>The page should only be accessible from the www. site. Pages should not be accessible from the CNAME domains.</p> <p>I have tried to put a mod rewrite in the .htaccess file and I have also tried to put a exit() in the main script file.</p> <p>But when Cloudfront does not find the static1 version of the file in its cache, it calls it from the main site and then caches it.</p> <p>Questions then are: </p> <pre><code>1. What am I missing here? 2. How do I prevent my site from serving pages instead of just static components to cloudfront? 3. How do I delete the pages from cloudfront? just let them expire? </code></pre> <p>Thanks for your help.</p> <p>Joe</p>
