Urgent assistance needed with ClickJacking iRule or HTTP Policy to cover multiple domains

We have an SSO (Single Sign On) solution that front ends several applications that use iFrames. It is also accessed via different domains that go back to the same VIP. Granted I don't fully understand the X-Frame Options, I do know that when we used sameorigin it broke one of the applications. We then applied the iRule below specifying one of the URLs it worked for said URL; however when we discovered there was another URL we found out those users had not been able to access the site since it was not covered by the Allow from. Can a wildcard be used or can a condition that looks at the URL and then inserts the X-Frame Option to allow from specific to that URL?

SSO URLs https://sso1.site.com https://sso2.site.com

This worked when users access their applications behind sso1.site.com, but not sso2.site.com.

when HTTP_RESPONSE {
   HTTP::header replace X-Frame-Options "ALLOW-FROM https://sso1.site.com"
}

    Try this

    when HTTP_RESPONSE {
set host [string tolower [HTTP::host]
if {[class match  $host contains URLdatagroup]}
{
HTTP::header replace X-Frame-Options "ALLOW-FROM https://sso1.site.com"
}
else
{
HTTP::header replace X-Frame-Options "ALLOW-FROM https://sso2.site.com"
}

}
