We are using Akamai CDN as our load balancer and it also servers as a gatekeeper for requests.
We usually consume 3rd party services and in those cases whitelist their IP to be accessed in our servers. The service we are currently using cannot share IP since it is on cloud and keeps changing. They can either provide host name or Custom request header or a user agent.
I tried adding host entry but that did not work. Any idea how to add custom request header or user agent?
