You have "Use Full Friendly URLs" option enabled, however you missed out the notice below.

http://xenforo.com/help/friendly-urls/ (look at the information under 'Apache')

 

what is the option to get exact link www.thehinduforum.com rather than http://www.thehinduforum.com/index.php

 

Read the article I linked to above. The option 'Use Full Friendly URLs' exactly does this.

 

In a nutshell, rename htaccess.txt to .htaccess in your root forum directory. You may have to define the rewrite base in it (it is commented out) pointing to the base of your forum directory. Then select the friendly URL's option in the ACP.

 

Tracy, could you explain what do you mean by that? I haven't got it.

Reading all the guides and some topics regarding this subject, the thing I understood was: I need to rename the txt to .htaccess and simply change the admin CP to to full friendly url option.

 

It's documented in the htaccess.txt and why:

Code:

        #       If you are having problems with the rewrite rules, remove the "#" from the
        #       line that begins "RewriteBase" below. You will also have to change the path
        #       of the rewrite to reflect the path to your XenForo installation.
        #RewriteBase /xenforo
