Expression Persistence

Hank,

if you are entering the pool from command line (i.e. using bigpipe) you

need to put single quotes around the expression in order to avoid interference with shell globbing and expansion. The command should look like this:

b pool WIRELESSDEV-80 { select 'node(findstr(http_uri, "bigip=", 6) + ":80")' member 163.231.95.94:http ember 163.231.102.154:http }

If you are entering the select expression from the GUI, put just:

node(findstr(http_uri, "bigip=", 6) + ":80"

into the "Node SelectExpression" field on the Pools->Pool->Persistence

page.

The pool statement should work exactly as you have it when entering the configuration by manually editting /config/bigip.conf.

I've tested all of the alternatives on BIG-IP 4.6.4 and all of them worked for me 🙂
