how to extract parameters from Jmeter for web forms using redirection

问题

Hi so my webform navigates from : http://43.252.88.109:4006/BracketICT/?t=aZCcbzidJJKfFgrkk1RYPH0zHTl+MtTuoGeiUw0hEw48nLZUoPrfntO29VV2daEiR3cPbu25/Xf2a3Q1UMZs1tAoUDti4wBVbYQbRHhhBDTt0Z1yTrWlkWKunP18DkVBkRSSVMdiHYyQ=&uniqueID=dGdck61pZFirpz9fA5FQZFhakSeoICZ9&dev=1696661 to http://43.252.88.109:4006/BracketICT/examstart.aspx ]3 i.e. from the instructions page to exam start page on the click of ![the exam start button. My Jmeter response during recording shows that the link: http://43.252.88.109:4006/BracketICT/examstart.aspx accepts two parameters i.e. attemptid or recordid. These values are generated on the location parameter of the examstart screen when the user clicks on starts test and lands on exam page. My response for http://43.252.88.109:4006/BracketICT/examstart.aspx does not show the location parameter on JMeter. How do i extract attempt id or recordid dynamically in this case during redirection ?]5

You need to:

1. Expand the 3rd sample result from the top in the View Results Tree listener

2. Switch to "Response Headers" tab

   there you should be able to see the Location header and you will be able to extract these attemptid and recordid values using Regular Expression Extractor
