"Select pool based on uri content" iRule doesn't seem to be working

Thanks Aaron,

 

 

I have swapped the hyphen with and underscore and that seems to have resolved that issue.

 

 

I also replaced the "foreach" loop with a cleaner "findclass" command (shown here)

 

 

====old way to set variable==

 

foreach line $::esb_svc_name-port_class {

 

if {[string match [getfield $line ":" 1] $svc_name] } {

 

set svc_name_port [getfield $line ":" 2]}

 

}

 

====================

 

 

====new way to set variable==

 

set svc_name_port [findclass $svc_pool $::esb_svc_name_port_class ":"]

 

====================

 

 

Here is what the iRule now looks like

 

 

===========current iRule iterration=============

 

when HTTP_REQUEST {

 

pool esb_8981_pool

 

 

set front "esb_"

 

set back "_pool"

 

 

set svc_uri [getfield [HTTP::uri] ? 1]

 

set svc_name [getfield $svc_uri "eProxy/service/" 2]

 

set svc_pool [concat $front$svc_name$back]

 

 

set svc_name_port [findclass $svc_pool $::esb_svc_name_port_class ":"]

 

}

 

 

when LB_SELECTED {

 

log local0. "==ESB Tibco: initial lb selection is [LB::select]=="

 

 

if { ([LB::status pool [LB::server pool] member [LB::server addr] [LB::server port]] eq "up")\

 

and ([LB::status pool $svc_pool member [LB::server addr] $svc_name_port] eq "up") } {

 

eval [LB::select]

 

 

} else {

 

LB::reselect

 

}

 

log local0. "==ESB Tibco: final lb selection was [LB::select]=="

 

}

 

======================================

 

 

It seems to be working as expected, except that when I look at the logs created, it seems to be reselecting the node to which traffic is being sent to even if both of my comparison values are TRUE.

==================================

 

 

The reselection is interesting and I'd like to figure that out as well.

 

 

Thanks again for the assistance.
