How do I read chunked HTTP responses on jmeter?

Question

I am using jmeter to send a HTTP POST request. the server responds with a chunked http response 200 ok and I need to parse the initial chunk. However jmeter waits for all the response chunks. I tried with the http sampler and http raw request sampler. In both cases the chunks are not parsed individually.

Answer 1

It can be achieved only by using JSR223 Sampler and custom Groovy scripting (or alternatively writing a brand new JMeter Plugin)

Example code you can use as the basis can be found in How do you read and print a chunked HTTP response using java.net.http as chunks arrive? answer
