Cloudflare Optimization & Troubleshooting

What this case study is based on

Completed Upwork engagement supplied by Xequent. Only what the project record actually shows is stated here. Where no measurable outcome was recorded, none is claimed.

The security problem

• Cloudflare configurations can become difficult to troubleshoot when DNS, proxying, caching and security controls interact.
• Optimization requires understanding the existing configuration before changing it.

Technical approach

The specific controls follow from the site's architecture and its observed traffic, never from a template. The workflow below is the reasoning behind the work, described at the level the project record supports.

1. Review the existing Cloudflare configuration and identify the actual source of the problem.
2. Trace DNS and proxy behavior before changing application settings.
3. Check WAF and firewall rules for conflicts and unintended blocking.
4. Apply the smallest useful correction and validate the affected path.

Result and client evidence

• The client gave the engagement a 5.0/5 rating and described the experience positively.

A Cloudflare setup is a configuration, not a switch

Turning Cloudflare on puts a site behind a proxy. It does not decide which requests belong to customers, which belong to scrapers, and which belong to someone probing your login or checkout. That judgement lives in the rules, and the rules have to match how the application actually behaves.

Which is why rules go out in log mode first and get checked against real traffic before anything is set to block. Managed rules left at defaults catch generic scanners while routinely breaking file uploads, rich text editors and API clients. See WAF setup and integration fixes for how that is handled.
