Identifying the Provider

When using the IO River service, you may sometimes need to check which CDN provider is serving your traffic. You can determine this by inspecting the x-ioriver response header. Any traffic served via IO River includes the x-ioriver header, which indicates the provider handling the request.

If you have Traffic Policies for specific geolocations, you may want to send HTTP requests from those locations. You can use a VPN to achieve this.

Identifying Using curl​

You can use the curl command to send an HTTP request to your service and check the x-ioriver header to see which provider handled the request.

For example, the following curl command shows that the request was served by Fastly:

curl -v https://www.example.com
...
< x-ioriver: Fastly

Identifying in the Browser​

You can also identify the provider serving the HTTP request using your browser. If you are using Google Chrome, follow these steps:

  1. Open Chrome and launch the Developer Tools (F12 or Ctrl + Shift + I).
  2. Navigate to the Network tab.
  3. In the browser, go to the URL you want to test.
  4. In the Network tab, locate the requests made by the browser:
    • Find the request going to your domain.
    • Click on the request and scroll to the Response Headers section.
    • Look for the x-ioriver header in the response headers.
