Assuming I'm understanding your question (you want to get the 
path of a URL after redirects), if you're not adverse to 
dependencies you could use requests; 
https://code.dlang.org/packages/requests.

Create a Request, query an URL for a Response and then access its 
finalURI member. Then parse the path string normally to get the 
session ID, such as with std.algorithm.findSplit and friends or 
with regex.

import requests;

Request req;
Response res = req.get("https://website.com/");

string id = res.finalURI.path
     .findSplit("?s=")[2]
     .findSplitBefore("&")[0];

if (!id.length) { /* no ID in URL */ }
