Disable zoom on input focus in Android webpage

The following worked for me (Android Galaxy S2):

<meta name="viewport" content="width=device-width, height=device-height,  initial-scale=1.0, user-scalable=no;user-scalable=0;"/>

Not possible!

I've got some bad news for you all. It's now been 6 months and no one has correctly answered the question.

Also I've finished working on that project and employer.

I'm afraid to say it, but exactly what I asked for is impossible. Sorry peoples. But I'm going to leave the question alive so people can see the other options.
