Goldhen is a type of exploit or hack that targets the PlayStation 4, allowing users to potentially jailbreak their consoles or run unauthorized software. Specifically, the "1150" refers to a particular version or iteration of the Goldhen exploit, designed to work with PS4 firmware version 1150 (or 11.50, which corresponds to a specific software update).
No. Unlike firmware 9.00 or 5.05, firmware 11.50 cannot be jailbroken by simply visiting a website. You must use the PPPwn Ethernet exploit from a PC every time you restart your console. There is currently no "self-hosted web link" for 11.50. goldhen ps4 1150 link
