Introduction

Testing new versions of Prebid.js in a production environment can be risky, potentially disrupting live ad operations and affecting ongoing campaigns. The difficulty lies in validating the new version without impacting the current setup.

Requestly offers a solution by enabling you to test new Prebid.js versions safely by redirecting requests, ensuring minimal disruption and accurate validation.

Load new version of Prebid.js

The Redirect Rulein Requestly allows you to redirect requests to a new version of Prebid.js instead of the live version. This is particularly useful for testing updates and validating configurations in production, without disrupting ongoing ad operations.

Load new version of prebidjs
  • Another URL: You can redirect the request to a different URL. In this case, the redirection is happening to a new JavaScript file URL.
  • Local File: This option lets you redirect to a local file stored on your machine.
  • From Files/Mock server: You can also choose to redirect the request to a file hosted on a mock server or from files you’ve set up.
  • Source Condition: This determines which requests will be redirected. Here, any request containing https://example.com/prebid.js will be redirected.
  • Destination URL: This is the URL where the request is redirected. In the example, it’s redirecting to a new debug script.
  • Test URL Condition: You can check if the rules you’ve set up work correctly by testing them on specific URLs.
  • Filter Out Condition: You can apply filters to limit which requests are affected, making sure only the ones you want are modified.
