At OWOX BI, we're all about enabling accurate real-time user behavior tracking for effective marketing strategies. Our latest enhancement takes this commitment further with the addition of preflight request processing in OWOX BI Streaming.

Context: CORS mechanisms and Data tracking

Accurate data collection is crucial, but sometimes technicalities like Cross-Origin Resource Sharing (CORS) can complicate matters. Browsers perform CORS checks, involving custom headers (for instance, "Traceparent"), often triggering preflight requests. If a preflight request doesn't receive a correct response from the server, it can lead to CORS errors. These errors have the potential to disrupt data collection.

Release insights

We're excited to announce that OWOX BI Streaming now handles all preflight requests seamlessly. This means data tracking from your website remains uninterrupted, providing you with the insights you need for informed decisions. By addressing preflight requests, we're ensuring that your real-time user behavior tracking experience is as smooth as possible.

If you have any questions about using the new preflight request processing feature or need assistance, don't hesitate to contact our support team at
