SFTP client path map to different Pool members individual path

hi

we need to create irule for sftp. requrement is as under: 1) sftp push client will connect via sftp client to our Virtual server VS IP: port sftpclient ------sftp:path /export/home/input/---- VS:1.1.1.1:22--------sftp----(pool:server1:22 path:/export/home/user/server1/input & server1:22 path:/export/home/user/server2/input)

what we need to map the sftpclient requested path (/export/home/input/) to each pool member individual path , where one will be active and other will be standby,

if ther server 1 is active then then he can push the file to respective location on server1

2) sftp pull

client will connect via sftp client to our Virtual server VS IP: port sftpclient ------sftp:path /export/home/out/---- VS:1.1.1.1:22--------sftp----(pool:server1:22 path:/export/home/user/server1/out & server1:22 path:/export/home/user/server2/out)

need your support how this can be done
