Irules with parameter values in target url

One way to do this is like below,

datagroup with values of target host with full uri. As URI involves query parameter, planned to call the complete URI itself. Note the host and and URI are split by "|" in the data value.

ltm data-group internal /Common/test_dgl {
records {
mysite.one.com {
data "mysite.second.com|variable?PartnerIdpId=http://team02.com"
}
}
type string
}

Irule: On the irule, using the "|" as a delimiter.

ltm rule test_rule {
when HTTP_REQUEST {
set data_value ""
set newhost_value ""
set newuri_value ""

if { [set data_value [class match -value [HTTP::host] equals test_dgl]] ne ""} then {
set newhost_value [getfield $data_value "|" 1 ]
log local0. "New HOST Value is $newhost_value"
set newuri_value [getfield $data_value "|" 2 ]
log local0. "New URI Value $newuri_value"
 Do something 
}
}
}
