Google is using these two urls as totally different.

Can fetching both in google webmaster will take care of the problem?

Also these are coming from an external link.

Hi Tanveer,

Please allow me to share a different approach:

http://www.abc-directory.com/site/4381910http://www.abc-directory.com/sitE/4381910The first URL works, the second does not. Why? These are two different URLs. Both Google and SEOmoz understands these are two different URLs. As a human, you perceive the above two URLs as being similar. To a crawler, these are two completely different URLs which are fully capable of displaying completely different information. A similar related topic relates to adding a trailing slash to a URL. http://www.aa-rental.com/Audio_rental.asphttp://www.aa-rental.com/Audio_rental.asp/The above two URLs are seen as different. A fantastic explanation can be seen here: http://googlewebmastercentral.blogspot.com/2010/04/to-slash-or-not-to-slash.html

The same concept which governs the trailing slash applies to capitalization.

My server actually supports both upper and lower cases. IT is not google webmaster that is giving me this error, they are coming from seomoz crawler.

Do you think fetching both upper and lower cases will fix the issue in google webmaster.?

The behavior you are describing is normal for Google. Those are two unique URLs.

Many of us live in a Windows-based world whereby capitalization is interchangeable. In HTML, an upper-case R is represented by R whereas a lowercase r is represented by r

The two URLs you shared represent two different locations. You may choose to configure your website or webserver to serve users the same webpage, but that is not required. You can choose to provide completely different content on those two URLs. Google knows this and therefore views those URLs independently.

The recommended approach is to always use lowercase letters in your URLs. Otherwise, I would suggest adjusting your server settings to correct the issue.
