Add a proxy URL checker to massscan

Hi, I am using the famous masscan tool: [login to view URL] it works flawlessly. but i need to add to it after finding an open port a URL opener. Means, I want to check if the open proxy founded by Massscan it can open a specific webisite choose. so its just like adding a tweak to Masscan programing to check specific URL if found open port. is that possible? because Masscan, is a decent in multi threading which i like.
