FTP LB & content switching base on file extension(exe mov etc).

Hi swjo,

I see a chance for you to write an iRule to balance the request based on the requested ressource. Below are some ideas for your project...

1. Balance the initial FTP request to your pool as usual...
2. Capture the initial user logon and any session information (e.g. port mode, etc.) for replaying to the individual FTP servers.
3. Listen for any RETR commands (file download) and evaluate the contained file extension.
4. LB::detach and reselect the node based on the file extension.
5. Replay the initial user logon and session information to the new server.
6. Replay the RETR (file download) command...
7. Repeat at step 3.)

Cheers, Kai
