Always show mobile version in safari OS X I do not know where to public my question and in fact i hope that it is the right place :)

I really like mobile version of one web site, but at the same time i hate full version of it. Is it possible to make redirect in safari on my OS X? Possible do you know some extensions, tips and etc.

I checked ip adresses of that two version and they are the same. So i cannot just edit the hosts file.. Hope you know a solution. Thank you.
You have to enable the Develop menu of Safari, then you can choose your user agent.
