jmeter regular expression extract part of returned url

Question

I need to extract a part of returned url from a GET Request. As the following :

https://happy.new.year/idp/1Z8a8/resumeSAML20/idp/startSSO.ping    

I need to extract this value: 1Z8a8 and I need to put it into a new POST request.

Which regular expression do I have to use in regular expression extractor configuration?

Answer 1

You could use this:

(.+?)\/

This will match the parts between slashes. The one you want is the fourth match.
