📚 Description

Cloudflare Web Analytics currently rewrites browser beacons through the app's server proxy. On Workers, those requests return HTTP 204 while almost no events reach Web Analytics.

Remove proxy support for this integration and retain script bundling. Cloudflare documents that RUM cannot collect Worker subrequests. The regression test executes a bundled beacon and checks its actual collection destination.

Update the integration documentation and proxy support table to describe direct collection.

📝 Walkthrough
📝 Walkthrough

Walkthrough

Cloudflare Web Analytics no longer declares proxy support or an IP-only privacy setting. The documentation describes direct browser collection and explains that Worker proxying cannot collect RUM events. A new transport test checks beacon delivery to the Cloudflare RUM endpoint, and proxy configuration tests no longer expect a Cloudflare Web Analytics proxy.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes


Merge Risk: ⚪ Minimal · up to 9c78c

Cloudflare Web Analytics is documented for direct collection rather than the IP-only proxy preset, and the previously identified table inconsistency is corrected.

139-139: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Remove CF Web Analytics from the PRIVACY_IP_ONLY list.

Line 139 is unchanged in this PR. It still lists CF Web Analytics as a user of PRIVACY_IP_ONLY. The registry no longer assigns that preset, and Line 164 now shows n/a. The two entries disagree, so the preset table is stale.

Line 141 also lists the scripts that have no proxy capability. Add Cloudflare Web Analytics to that list.

Cloudflare Web Analytics to the no-proxy-capability scripts list on line 141.
Keep the entries consistent with the registry’s current `n/a` assignment.
