calling main domain content into subdomain

Rewrite Rule for sub and root domain

[agriz]

Hi,

I will explain what i need...

If any user type

[sub1.domain.com...] -> It should not redirect. But just get the content form [domain.com...]

[sub2.domain.com...] -> It should not redirect. But just get the content form [domain.com...]

[subn.domain.com...] -> It should not redirect. But just get the content form [domain.com...]

How can i right such a htaccess code?

Any help is appreciated

Thanks
