Do a resource download network, download resources can not access, technical solutions

The most recent resource download network, upload files to the development folder, no encrypted files, but the download can be directly accessed directly through the address, thus adding the. htaccess file prevents direct access to the download, but it cannot be downloaded when the program is read. I just copy the original download directory files from the program, but this is inefficient, so that the duplication of replication and so on, there is a good solution, whether the cache can be used to cache the downloaded files? If the line, how the code is written. My brother is not technically enough

This I also use, but can not download, I now the purpose is only through the program download, if this is used. htaccess file programs are not available for download

The uploaded file is placed on the top level of the site directory and is read and written by the program.

The downloaded code has a header or something. Use that on the line, seemingly, not very sure, with the actual results prevail
