Thanks for the suggestion milosevic... I tried what you suggested and maybe we are getting somewhere:
I checked the http headers through 4 different applications + fetch as GoogleBot (from WT)+ seo-browser. All applications show normal (i think) results like:
HTTP/1.1 302 Found

except from 1 application which shows:
#1 Server Response: http:/
/[my site]
FollowRedirects=False; Server requested redirection, but sent no new location.
What is this and how do i change it to True?
Also, another info that might be important. There is a script that redirects the user according to the browsers language.
