I am 77days! I am quite curious and needs to know can I do the task I told in the title. But if still confused here is an explanation: I am currently trying to make it so on website visit the file starts downloading now you'll be like which file? Like if you do mysite.com/meshes/star.obj

Now if you visit this webpage, instead of giving structure details the webpage enforce to download the file in the domain/link. Now the issue is I dont know how I can do that using PHP or HTML! Thank You!
