Jmeter - get entire query string into variable

Question

Is there a way to use the Regular Expression Extractor to grab the entire .NET encrypted query string and place it in a variable? Example, for URL via a GET:

https:/www.website.com/folder/page.aspx?jfhjHSDjgdjhsjhsdhjSJHWed

I am trying to have ${myQueryString} = jfhjHSDjgdjhsjhsdhjSJHWed so I can replay it later in the test plan by appending the variable to a future GET.

Answer 1

(?<=\?)[^?]+$

will match everything after the last ? in the string. I hope that's what you meant.
