Amy asked: "is there any way to modify the http response for query? (So =
that I can track the query result)"

What do you want to modify? You know which one you queried from the port =
number. The longer answer is that to modify the result or the response =
body you will need to modify the template you are using.

Hello everyone,

I want to do some A/B test on the algorithm, and have found the =
following method:
Run two engines in parallel (with different port of course), with the =
same appid.

However, I want to use some load balance to redirect the traffic from =
clients to the engines, and also tracking the recommendation algorithm =
(in order to analyse the result). And here the question comes: is there =
any way to modify the http response for query? (So that I can track the =
query result)

Thank you for any advice!

Best regards,
Amy
