Hello All,

Following is the code, expecting 10 HTTP requests, but the summary shows 18 HTTP requests.

import http from 'k6/http'

export default function () {
  **for (let id = 1; id <= 10; id++) {**
    http.get(`http://example.com/posts/${id}`);
  }
}

Hi @BharathM,

I would expect there will be some redirects as discussed in your previous question.

If I run the specific test code it gives me 10 requests exactly, so i can’t tell you what happens in your case to have 8 redirects and 2 not redirect :person_shrugging: .

I would recommend using -o json to see what request metrics are emitted- those will also include status codes and or use --http-debug or even the newly added way to dump SSL keys and use wireshark to see exactly what is being send and received.

In all of those questions you will probably pretty quickly find out why there are 18 requests
