This article explains how to configure a SiteBacker probe to follow HTTP redirects.
It applies when a monitored endpoint returns a redirect response and SiteBacker is reporting the pool record as unavailable.
When to Use This Article
- Your monitored URL returns a 301 or 302 redirect.
- SiteBacker is marking a working URL as failed.
- You recently implemented redirects on your application or web server.
Why Redirects Can Cause Probe Failures
If a SiteBacker HTTP probe encounters a redirect response and is not configured to follow redirects, it may interpret the response as a failure.
Enabling the redirect option allows the probe to follow the redirect and evaluate the final destination response.
How to Enable Redirects in a SiteBacker Probe
- Login to UltraDNS.
- Click on Domains.
- Click on <domain.com>.
- View the Filter On Type drop down menu and select Sitebacker.
- Click Expand All to view all the resource record types to view all Sitebacker pools.
- For any pool, click the pencil to the left of any Pool Record.
- Click Probe Definitions.
- If you don't have a Probe configured, click Add Probe.
- Click Select Pool Type and choose HTTP.
- Click Select Host to choose the Pool Record.
- Click Select Probing Regions to choose the Regions (at least 2 have to be selected).
- Select Probe Interval to choose from 30 seconds to 15 minutes.
- Under HTTP Probe Transactions, click + Add.
- Set the other details as needed and be sure the Follow Redirect is set to Yes, then press Done.
- If you do have a Probe configured, click the pencil next to it.
- Be sure the Follow Redirect is set to Yes, then press Done.
Verification
After enabling Follow Redirect, monitor the SiteBacker pool status.
The probe should follow the redirect and mark the resource as healthy if the final destination returns a successful response.
Important Notes
- At least two probing regions must be selected.
- Ensure the final redirected URL returns a successful HTTP response.
- Use the ? help icons throughout the portal for additional field-level details.
