Apache X-Frame-Options Allow-From multiple domains

I got a error when i using x-frame headers option with apache.

Header always append X-Frame-Options ALLOW-FROM site1,site2,site3

or

Header always append X-Frame-Options ALLOW-FROM=site1,site2,site3

or

Header always append X-Frame-Options ALLOW-FROM=site1
Header always append X-Frame-Options ALLOW-FROM=site2
Header always append X-Frame-Options ALLOW-FROM=site3

How could i set the X-Frame-Options: ALLOW-FROM to support more than a single domain?

Thanks!

Solution 
  • Header always append X-Frame-Options ALLOW-FROM=site1
Header always append X-Frame-Options ALLOW-FROM=site2
Header always append X-Frame-Options ALLOW-FROM=site3

    This way is OK.
    But I got an error when i first using it.
    Maybe i make a wrong character.
