Missing X-Throttling-Control header

[pierreb]

Dears,

we observe that teh X-Throttling-Control is no more provided in the responses headers.

This doesn't seems documented as an API change.

Does anyone know if the instantaneous rate-limiting was removed or the header syntax changed ?

thank you,

Hi,

We would not intentionally remove any such thing. Can you send me an example of one such header? Please send it via email so that I can investigate further. In the email, please add your OPS user name as well.

Thank you in advance,

Hi,

Thank you for your quick request.
I think that i understood when i miss this field :
- When i send query1 for the first time : X-Throttling field is available.
- When i send the same query when Age(header parameters) is set and Age<maxAge : X-throttling field is not available.

Hi,

Here is some information about missing X-throttling header in some responses:

Some responses are delivered from Cache before the request hits the application server (when it is the same server that dealt with the previous response). Caches do not retain the HTTP headers produced with the response and so the cache hit is delivered without an HTTP header.

Under these circumstances, the client code should assume that the request had no impact on the traffic throttling metrics.

Kind regards,
OPS support,
