@idettman This pull-request appears to be pulling in changes not related to GDPR in the file diff. Might need to be rebased.

@idettman The adapter file changes look fine. But it seems there are conflicts now in the PR against master.

Can you please review and address the conflicts, as well as comment on Rich's feedback? Thanks.

@idettman Also, can you submit a docs-PR to update the Rubicon bidders page with a new variable named gdpr_supported: true? It can go right under the variable for prebid_1_0_supported.

This would allow the Rubicon adapter to show-up automatically on a list we have setup for GDPR supported adapters in the docs. Thanks.

Rubicon Adapter Docs Update: prebid.github.io #719

[jsnellbaker]

@idettman Thanks for submitting the docs PR. When the other Rubicon GDPR PR was merged, it seems like it created some additional conflicts here. Can you please take a look again and see if we can get in sync with master? atm a number of changes look like they're going to be reverted in master if we were to merge as is. Thanks.

Merged changes to latest master updates

[jsnellbaker]

@idettman In the upcoming changes to the consentManagement module, we'll be renaming this field to bidderRequest.gdprConsent.gdprApplies

Can you please make the necessary changes to point to the new field? Please also ensure you're pointing to the bidderRequest object and not the bidRequest object.

As a final request, can you please make the above updates on the earlier set of GDPR code in the adapter file (for the video requests)?

[idettman]

Requested changes are committed.

What happens if the consent is not asked to the user? What's the default used by Rubicon?
