I'm attempting to do clientIP based persistence on a 180e running
10.30.7.

The persistence works fine with pbind client for HTTPS, but when a user
connects using FTP they will not the server affinity from the HTTPS
session on the new connection. I'm using both hash metric and clientIP
pbinds on all services.

Is there any way to make the persistent sessions carry over to
different services?

/c/slb/real 3
ena
rip 10.0.70.21
/c/slb/real 4
dis
rip 10.0.70.22
/c/slb/group 2
metric hash
add 3
add 4
/c/slb/virt 1/service https
group 2
pbind clientip
dbind ena
/c/slb/virt 1/service ftp
group 2
ftpp ena
pbind clientip

You don't really need to have pbind clientIP enabled for those services
if you are using hash. In fact it's not recommended as it creates
redundant persistent session entries. Hash uses the source IP, as long
as the source IP doesn't change then your FTP and HTTPS sessions should
hit the same server.

If you plan on using pbind clientIP with RR or LC metric then there is
no guarantee that FTP and HTTPS will hit the same server. However, HTTP
and HTTPS ARE bound together by pbind clientIP. This is required fro
shopping cart persistence.

Is your user behind a proxy server? Some ISPs will not proxy HTTPS but
will proxy HTTP, FTP, etc. The 180e will see two different IPs from the
same client.
