Hello,
Is there any method to call Moodle redirect function and create a POST redirect action? I'm using Moodle 2.6.
Best regards!
The answer is No, not just in Moodle, but in the HTTP protocol which all web sites use.
The only work-around it to use javascript: Make the first HTTP request return the HTML of a form with hidden form fields for all the POST data, and some java-script to auto-submit the form onload.
