I'm trying to do a simple login to moodle using Jmeter and I'm getting the same output that you did:
<div style="margin-top: 3em; margin-left:auto; margin-right:auto; text-align:center;">This page should automatically redirect. If nothing is happening please use the continue link below.<br/>
Please, would you be so kind as to help me by telling how I should configure the HTTP Request.
I really appreciate any help you can provide.
