Tip for dealing with session IDs in URLs

Brian Armknecht gives this tip for dealing with session IDs in URLs:

The nucat command wasn't working because the URL required a session ID that changes periodically. The new version of the command visits the page, scrapes the new session ID, then includes it in the search URL. I think it's sort of a cool trick.
