Today i got a mail from someone asking for a link exchange with a PR5 site resource page, http://www.example.com/resources/index.html
But the strange thing is when i tried to open the page in my browser, i saw momentarily it was http://www.example.com:80/resources/index.html and after that it changed to http://www.example.com/resources/index.html
what is that :80 for... a redirection!
Also just qurious to know, does link juice come from igoogle page, coz, i checked, there was no "nofollow" tag present.
