Load Balance SFTP based on destination File Directory

Hi,

Question that I can't find the answer for. Is it possbile using F5 Big-IP LTM to load balance 2 SFTP servers based on the file directory part of the URI String. I.e.

Incoming:

sshftp://FTPserver.company.com:22//parent/incoming1  --> Goes to SFTP Server 1

sshftp://FTPserver.company.com:22//parent/incoming1 2 --> Goes to SFTP Server 2

Access is open (i.e. we don't use usernames/passwords) as security is established via IPSEC tunnel prior to traffic hitting F5. This is not directly open to the internet.

Thank you all for your help.
