I want to send URL (PATH) as /controller_1/1/
/controller_2/2/start
But the parameter #2 of controller_2
is dynamic.
How to send that parameter?
make the parameter a variable: /controller_2/${controller2_parameter}/start
Then you define the value of ${controller2_parameter} wherever and however appropriate: a CSV dataset config, using a regular expression extractor to scrape from a webpage, etc.
