301 url redirect code for prevention of mirror sites

[clauf]

Hello,

 

I learnt that to prevent website stolen by mirror sites, can add some 301 redirect code in htacess file.

 

I know the code for redirect http://www.example.com to http://example.com. But what are the codes to prevent mirror sites and redirect those mirror sites back to you own site?

 

As this thread shows: http://www.prestashop.com/forums/topic/46460-solvedsite-copied-and-hacked-by-chinese-company/page__gopid__595240#entry595240

 

 

Thanks.
