handle multiple domains with Access-Control-Allow-Origin header in Apache

Question

I want to configure apache for cross-domain access header. I have tried multiple combination as suggested on number of threads on the forum. But its not working for me.

Answer 1

Unless I'm misunderstanding the manual, it should be:

Header always append Access-Control-Allow-Origin: "example1.com"
Header always append Access-Control-Allow-Origin: "example2.com"
Header always append Access-Control-Allow-Origin: "example3.com"

The manual states that the set and add actions behave in the following way:

set: "The response header is set, replacing any previous header with this name"

add: "...This can result in two (or more) headers having the same name. This can lead to unforeseen consequences..."
