Hi all

I'm new to zapproxy (2.16.1), and I'm using it in command line like this :
./zap.sh -cmd -quickurl https://www.example.fr -quickout /tmp/zap_exemple.md

Now I reach 429 for my target and I would like to apply some kind of rate limits

According to "network addon", doc https://www.zaproxy.org/docs/desktop/addons/network/options/ratelimit/ , it seems possible to do that per rule and per host

But I didnt find the way to inject a proper additionnal configuration options to command line to do that.

Is it possible to point me the right doc ?

or else (it would be great to improve it :p)

then show me a quick sample on how to use quickurl option and using a rate limite of max 5 request per second for "example.fr" host

Best regards

It w

The quick start command line option is _very_ limited.

Normally if you want more flexibility then I'd recommend the Automation Framework, but that doesnt support rate limiting directly yet either :/

For a comparison of the automation options see https://www.zaproxy.org/docs/getting-further/automation/automation-options/

Right now your best option to support rate limiting is via the "config" options.

They are not officially documented but we do provide a FAQ to help you work out what values to use: https://www.zaproxy.org/faq/how-do-you-find-out-what-key-to-use-to-set-a-config-value-on-the-command-line/
