This was the only way I found to both protect and transfer very large files with PHP gigabytes. It's also proved to be much faster for basically any file. Available directives have changed since the other note on this and XSendFileAllowAbove was replaced with XSendFilePath to allow more control over access to files outside of webroot. Download the source. If you are looking for an algorithm that will allow you to download force download a big file, may this one will help you.
I have seen a lot of download scripts that does not test so you are able to download anything you want on the server. Test especially for strings like ".. If possible only permit characters a-z, A-Z and and make it possible to only download from one "download-folder". Using pieces of the forced download script, adding in MySQL database functions, and hiding the file location for security was what we needed for downloading wmv files from our members creations without prompting Media player as well as secure the file itself and use only database queries.
Something to the effect below, very customizable for private access, remote files, and keeping order of your online media. Of course you need to setup the DB, table, and columns. However, if this setting is checked, and browser windows are being re-used, then it will open up on top of the page where the link was clicked to access the script.
But, if the setting is unchecked, the output XML file will open up in a new window and there will be another blank window also open that has the address of the script, in addition to our original window. This is far from ideal, and there is no way of knowing whether users have this option checked or not.
But there are some headers, which PHP itself outputs automatically, disturbing this. So I wrote this function with erasing these. If you are using the procedures outlined in this article to force sending a file to a user, you may find that the "Content-Length" header is not being sent on some servers.
The reason this occurs is because some servers are setup by default to enable gzip compression, which sends an additional header for such operations.
When this script is run I get a 'unable to open file' error. I realise that this can work perfectly if the XML file is located on the server but if anyone has any ideas on how to read from a file on the client side you will surely make my week!

Hhowever, the PHP server could read the file if it were mounted on some kind of network drive a share under windows for example , or if the local machine also had a web server running which could serve up the file to the remote machine.
If you want a longer discourse write back! Its looks like I will have to try something else. Might be a good read: The application is a php based request tool that has two types of users, regular and admin. Any admins that are logged in on separate machines will have a pop up appear that'll say New Request Added, they sort the problem and submit a response. The theory is to stop people randomly approaching us physically and asking stupid questions when they fell like it.
Make it electronic to allow a bit of control.
