www Redirect Loop on a Website: How an AI Agent Traced It to a Cloudflare Redirect Rule Instead of the Web Host
A client reported that the www version of their website would not load. The quick assumption is that the web host is broken. The agent read the raw responses, showed the request never reached the host at all, and pointed to a single misconfigured Cloudflare rule. It was corrected the same day.
What was getting in the way.
A modern website passes through several layers before it reaches a visitor: the domain's settings, a service like Cloudflare in front, and the web host behind it. When the www address loops or fails, each layer's support team can truthfully say their part looks fine. Hours go to tickets with the wrong company. Knowing which layer answered the request is the whole problem, and it normally takes someone who reads response headers for a living.
Context
A small business with a WordPress website on managed hosting and Cloudflare in front, reporting that the www version of its address had stopped working. Nobody on the team is a Cloudflare specialist. This is one of the most common failures after any change to a domain's settings.
How the work runs.
- 01
Ask both addresses the same question.
The agent requested the www address and the plain address and compared the raw responses side by side.
- 02
Read who answered.
The plain address carried the web host's signature in its response, so that request reached the host. The www response was signed by Cloudflare only, with no trace of the host.
- 03
Spot the malformed instruction.
The www redirect told browsers to go to the bare domain name with no "https://" in front. Browsers read that as a path on the same site, so they ask again and get the same answer.
- 04
Hold the conclusion up to a challenge.
A team member questioned the diagnosis. The agent went back to the raw responses and laid out the evidence line by line: the redirect was coming from Cloudflare, and the host never saw the www request.
- 05
Name the exact place to look.
A redirect rule or page rule in Cloudflare for the www address, written without the full destination.
- 06
Verify the fix from a clean start.
After the rule was corrected, the agent retested with fresh requests: www now redirected to the full secure address, and the site answered normally.
Evidence from the workflow.
Each system has a role.
the layer in front of the site, where the faulty redirect rule lived
Cloudflare
the web host, shown by the evidence to be working correctly
WP Engine
the side-by-side comparison of both addresses
Raw HTTP response checks
where the report came in and the evidence was posted

Why this is Operator.
Owns a workflow end to end, running the process inside the authority you set.
- 01
The diagnosis was read-only: public requests anyone could make. The agent presented evidence and a specific place to look. When its conclusion was questioned, it rechecked and showed its work instead of repeating itself, and invited contrary evidence.
Impact / Outcomes
The faulty layer was identified from two requests, without opening a ticket with the host.
The fix went to the right place and the www address was working again the same day.
The evidence was plain enough for a non-specialist to follow: who answered, and what the redirect said.
The retest confirmed a correct redirect and a normal page load, with no loop.
