Delay and Throttling Rules

Section titled “Delay and Throttling Rules”

Timing and throttling rules simulate slow networks and backend delays.

example.com reqDelay://1000
example.com resDelay://2000
example.com reqSpeed://10
example.com resSpeed://100

reqDelay delays before sending a request upstream. resDelay delays before returning a response to the client. reqSpeed and resSpeed limit upload or download throughput in KB/s.

Caveat: reqDelay only takes effect on TLS-intercepted (HTTPS) traffic; for plain HTTP requests it is currently a no-op. resDelay, reqSpeed, and resSpeed work on plain HTTP. Use HTTPS hosts (with TLS interception enabled) when relying on reqDelay.
