Extract string from the URL

Question

I want to extract a string from the URL. I have the following URL :

https://optim.actiontec.com/aei-api/users/R1RCQTY1MjA1MDYyMDc%3D

I want to extract the string after users/ and store it in a variable that I can use. I tried using the regular expression extractor but it did not work.

My second issue is extracting stuff from request headers. I dont know much about it but can we extract stuff from Request headers? This is my request header -

GET /aei-api/main/R1RCQTY1MjA1MDYyMDc%3D HTTP/1.1
Host: optim.actiontec.com
Connection: keep-alive
Accept: application/json, text/plain, */*
X-Token: 03a580b082140ee7
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36
X-User-Id: R1RCQTY1MjA1MDYyMDc=
Referer: https://optim.actiontec.com/
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.9

And I am looking to extract X-User-Id.I want to use the header value and pass it to other headers. Is it possible? Thanks

This is what I am using : /users/(.+?). Doing so gives me just the first charachter i.e R — Abhishek

The Regex configuration would be like this:

Field to check: Request Header
Reference Name: var
Regular Expression: X-User-Id: (\w+.)
Template: $1$
Match No: 1
