Simulate a slow origin — TTFB delay, no bot protection middleware
← Back to portalReloads this very page through /slow, which holds the whole document for the configured delay before sending a single byte. Extra query params are passed through untouched, so a rule matching them applies to the navigation request itself.
Fires one fetch or XHR against /slow/api (any sub-path works, e.g. /slow/api/checkout). The origin waits delay ms before responding at all, so the measured TTFB is the delay.
All enabled rows are fired in the same tick. Give each row its own path and query params so a rule can block some of them while the others keep hanging — the timeline makes the difference obvious.
