Colo location/code header

Hi all, first time here, how to get help and, eventually, being able to help.

I manage a legacy application which scalates very poorly. I’m wondering if there’s a way to add a header (like in some page rule) of which colo is dealing with connection to create a balancing rule in my on-prem nginx to redirect (based on which colo) to an application server in my infrastructure to attend a few specific colo locations.

I’m running Argo in Business Plan and the Country Origin doesn’t solve my problem.

Any ideas?

Thanks in advance.


The CF-Ray header will provide you with the details on the PoP from where the request came.

To a certain extent you could probably also load-balance based on the proxy addresses from where you received the request.


Thanks Sandro! The info is pretty good for me.

Now to the nginx.

Thanks again.
