Common Analytics Plugin : getNewRepeat plugin

[H_Kanchan]

Hi All,
I have installed the common analytics plugin and configured the getNewRepeatVisitor plugin to identify new Vs repeat visitors to my site.
I configured an evar to capture the value new / repeat.
Despite multiple visits to the site, I could see only "NEW" being passed to the evar. (instead of repeat)
Then in the cookies section, I noticed that the s_nr cookie, meant for the identification of repeat visitors, wasn't getting set.
I am not sure how to solve this.

By the way, I am testing the implementation and hence the site is running on my local host.

Thanks in advance for helping me out.
