Redirect subdomain to folder

    Hello it is not possible make a Redirect from a subdomain to folder ?


    Example:

    I have 1 Space. There are 3 folders on this space (Folder1, Folder2, Folder3)


    Each folder should redirect to another subdomain. (sub1.domain,sub2.domain,sub3.domain)


    I can only redirect a subdomain to another domain?


    Sense behind it is: I have 1 domain. But i would like to achieve several projects via subdomains. Project1, project2, Project 3 ...


    Thanks for Help
