Quota Download Tracker

The coding development will be done in php, what your constructing is download throttling and bandwidth quota / capping for the user via their cookie or session or http_auth. The user will download a file from the webserver, the download link will be streamed to them via fopen and content-deposited to the user, the stream will monitor the download of how many bytes is sent over http to the user. The stream monitor can be sql or a text file, mysql will be more effective. The throttle can be enabled or disabled , throttling meaning to limit their Download speed, the code will be OOP, the user downloads must be able to work effectively with a download manager such as internet download manager, dap, flash get or Jdownload, that means the user can stop their download link and resume in their web browser or the download manager, you can use http_range and fseek. The the major part in the coding is that the user will be limited on their bytes transfer depending on their traffic-share quota, that means if i set it to 1gb, the stream fopen(); will only give them 1GB else their connection link will stop until they recharge their download quota, meaning they will have to add more bytes to continue the file transfer. If they use a download accelerator with multi-connections, because the download manager usually splits the connection in various chunks, the code must detect how much threads the user is downloading at and how many bytes they have successfully download if they have exceed their bandwidth quota, the download will halt until they recharge their quota. All of this must be done in pure php. A Model example { Bandwdith transfer User login via cookie or php auth --> login () ---> user sends download link ---> [login to view URL] ----> searchesforthelink() --> sendsfile() ---> content-despoist --> stream monnitor() --> Writes the total amount of bytes transfred for the user --> Updates SQL. Sql ( id, filename, fileid, bytesused, userid, bytes_left, download_status) } These phpclasses will help you out towards this, i need to know whats the cost of designing this. { HTTP::Download Pear Class [login to view URL] [login to view URL] } If you have a better scripting language or program to code this application, let me know. I have some examples here that can help
