Allow gzip compress for BidRequest/BidResponse between prebid server and bidders

[vriffier]

Hello,

The prebid-server go is implementing this prebid/prebid-server#1812 compression.

Is there any plan on implementing the same thing for the prebid-server-java project?
Are there any bidder who can already read/interpret compressed bidrequest?
Any date on making this available?

Thanks,

[rpanchyk]

This one?
#1284

No from my understanding you're referring to response decompression whereas I was looking into request compression from PBS to Bidders

[rpanchyk]

We've global property for all outgoing requests - http-client.use-compression.
Full list - https://github.com/prebid/prebid-server-java/blob/master/docs/config-app.md#http-client
So, seems it is not possible to turn on for individual bidder (or request) since PBS uses only a few instances of HttpClient.

Hi @rpanchyk,

Sorry we are a bit unclear here :)

• Are you saying that it is possible to compress outgoing requests from the server to bidders using http-client.use-compression? Because we tested http-client.use-compression=true and it seems only to be used by bidders to compress their responses but it does not compress outgoing requests. Am I understanding this well? Or is that config supposed to be already compressing outgoing requests?

• If not possible, is this something meant to be implemented here: Allow gzip compress for BidRequest backend communication with bidders prebid-server#1812 ? (Question is for both Go and Java projects).

• Would any bidder be able to read compressed requests?

Thanks a lot for your help and sorry if this is already mentioned somewhere else! We are a bit struggling to be clear on this topic

hey @WalterT you're right - let me clarify.

Case 1: bidder responds to PBS with compressed body - if you set http-client.use-compression=true PBS will add ACCEPT_ENCODING header as described here - #288 (comment)
So, bidder exchange can respond with compressed body and PBS will decompress it.

Case 2: PBS requests bidder endpoint with compressed body - this one is not ready yet, but issue you've mentioned (prebid/prebid-server#1812) would be implemented in near future (sorry, no terms so far).
Please follow that issue for any updates on this case.
