Hi Everyone,
I'm looking for an elegant technology option to have telcos zero-rate
all of the traffic to a set of online destinations.
Can you clarify what you mean exactly by "zero rate" ?
What does it have to do with actions the proxy is performing?
Using an SSL
terminating reverse proxy could be a potential answer to this as we can
focus on zero-rating the proxy's downstream traffic with each ISP/Telco
without worrying about upstream servers.
There are two challenges to address here though:
1) Modern web applications on the upstream servers use many 3rd party
and X-a-a-S resources (e.g. embedded media, libraries, etc) that we
also want to pass through the proxy to ensure they are zero-rated.
To be clear; "reverse proxy" is just an old term for CDN frontend. It
requires public DNS records for the domains it services point all their
traffic to the CDN/proxy.
I'm not sure you are talking about the same thing. Maybe you are needing
an interception proxy or other QoS related systems.
In general;
a) If those upstream servers are doing XaaS fetches as their internal
operations there is no relevance to the gateway. It simply passes
traffic to upstream and they do their thing.
b) If those upstream servers are embedding URLs for clients to directly
contact the XaaS services. Then your desire is not possible without
redesigning the upstream service(s) such that they stop exposing their
use of the XaaS. Which often also means redesigning the XaaS service
itself too.
2) For a user to complete an end-to-end process they may get referred to
3rd party websites (like a payment gateway) that we only want to
zero-rate if the referral is from one of our designated upstream servers.
That is not possible for a reverse-proxy to do. It will never see the
third-party traffic, as mentioned by (b) above.
