HTTP referrer enables you to integrate your online surveys and tests with any website or service.
Referrer enables you to acquire information about the source (URL) from where your respondents came. It is working by default for all your surveys and tests, so you don't have to set any options to activate it. Collected information is available in individual survey reports and exported data.
You can customize referrer value by adding the referrer URL variable to your survey collector.
This will result in saving Blog as the referrer value into the response data.
NOTE. The referrer is based on HTTP header field called HTTP_REFERRER. We can't give any guarantee about this value as some users may block it in the web browser. To learn more about HTTP referrer please visit HTTP_REFERRER on Wikipedia.
Option available in the Professional and Enterprise plan.
