When traveling to other countries I notice that when I type in google.com to go to the homepage, it will detect that I am in a foreign country & will take me to the local version. For example when in Thailand, it redirects me to google.co.th & everything is in Thai script. Can I specify a specific domain I would like google to take me to, no matter which country I am in? And how does google do this, by detecting the IP address I am using?
That happens to me when I was in Thailand too, so I used this google link instead of google.co.th:
http://america.google.com/
just save the link to your bookmark or something 
or if you want it in other country, just go to google and type in "google _______ (name of country you want)" and search
I specified it in the browsers options panel (i.e. I set the home page to http://www.google.com) and it opens English google. I am in the Netherlands and if I just type http://www.google….. into the address bar, it goes to Dutch google.
Also, I use Avant browser.
