Rule not failing back to default pool

I am not able to get the following rule to fail back to the default pool if the widget_pool does not work. Any tips on where I am going wrong?

 

 

 

 

when CLIENT_ACCEPTED {

 

set default_pool [LB::server pool]

 

set default_snatpool [getfield [LB::snat] " " 2]

 

}

 

when HTTP_REQUEST {

 

set cache_pool "widget_pool"

 

set snat_pool "web_internal"

 

set used_cache 0

 

if { ([HTTP::uri] starts_with "/euf/") and not [HTTP::cookie exists "location"] }{

 

if { ${snat_pool} ne "none" }{

 

snatpool ${snat_pool}

 

}

 

pool ${cache_pool}

 

set used_cache 1

 

} elseif { ([HTTP::uri] starts_with "/gfe") and not ([HTTP::uri]

 

starts_with "/gfe/startup/")}{

 

if { ${snat_pool} ne "none" }{

 

snatpool ${snat_pool}

 

}

 

pool ${cache_pool}

 

set used_cache 1

 

}

 

}

 

when LB_FAILED {

 

if { ${used_cache} eq 1 }{

 

log local0. "[IP::client_addr] LB_FAILED for cache pool: '${cache_pool}' attempting to reselect on default: '${default_pool}' snatpool: '${default_snatpool}'"

 

if { ${default_snatpool} eq "none" }{

 

snat none

 

} else {

 

snatpool ${default_snatpool}

 

}

 

pool ${default_pool}

 

LB::reselect

 

}

 

}
