i would like to use mod_xsendfile but my home is a shared atmosphere which doesn't provide this type of module. processing large files for example videos via a server-side script and delivering it towards the browser this way appears to become unacceptable during my situation, and so i am searching for a method to enable per-file authentication in a way that's not likely to consume assets much. nobody shall understand what the particular path would be to the file they're installing. please suggest how to achieve that.
