I posted the following question on Super User : https://superuser.com/questions/537232/issues-with-htaccess-url-re-write
However this is not the original question , the original question seemed application specific and thus was marked as off topic and closed . I did some more experiments to determine where exactly I might be going wrong and now it is clear that it is not related to my application but to apache/htaccess/mod_rewrite thus it being suitable for super user . Please note the current question on the above URL holds no resemblance to the original question (which was down voted and closed) .
I request moderators/users with enough reputation to have a look at the question and reopen if it seems fit .
