use irule to match virtual server name to node name

Hi,

I combined your suggestion and write the following rule, but some errors occur, pls. help.

I am trying to replace the hostname in TCP payload and then pass to specify pool.

Check if the request hostname is WEBCSD0AN, change to WEBCSD01N and use pool WEBCSD01N_pool.

if request hostname is WEBCSD0BN, change to WEBCSD02N and use pool WEBCSD02N_pool.

Regards,

Ken
