Hi @pyakym
I assume that when you say header values you're referring to URL parameters? (if you mean actual headers, scroll to my bottom comment )
e.g.
abc.com/shop/checkout?headers=1
abc.com/shop/checkout?headers=2
In the VEC navigate to the page delivery options:
Click + Add a template Rule
And create logic to target multiple pages. Examples:
URL contains shop/checkout
URL contains ?headers=
This should ensure that you provide the same experience across different URLs/api versions.
If you by headers mean actual headers like response headers, then having different values in these shouldn't be a problem as Target will evaluate based on the URL and not the headers returned for the domain.
Let me know if I'm missing something obvious and the above isn't what you're looking for.
