RFR: Handle redirects manually

[Robin Westberg]

Hi all,

Please review this change that updates the webrev link verifier to handle redirects manually. Requesting the HttpClient to follow redirects automatically doesn't actually work in our case, not quite sure why. But we can work around it in the meantime.

Best regards,
Robin
