We have two websites and implemented SSO for one site. Now we need to implement SSO second website with different MetadataAddress&Wtrealm but we have an issue with
WsFederationAuthenticationOptions(){
MetadataAddress="",
Wtrealm="",
}

Every site has its own meta address and Wtrealm. How can we assign these values dynamically?

Site 1:

WsFederationAuthenticationOptions(){
MetadataAddress="abc.xml",
Wtrealm="site1",
}

Site 2:

WsFederationAuthenticationOptions(){
MetadataAddress="xyz.xml",
Wtrealm="site2",
}
