irule matching variable in uri

[southern_shredd]

We are having trouble with an irule that matches a value in a uri and send it to a different pool.

The value is the last 2 digits in the uri

example:

https://testinguri.dev.no:443/A2ABC/GT_1078_Human_v1/api/?env=02
https://testinguri.dev.no:443/C2CDC/GT_1095_Mail_v1?05
https://testinguri.dev.no:443/C2CDC/GT_2000_Process_v1?08

We are trying to match by this value and send the request to a different pool. If nothing matches it should go to the default pool

We tried a data group with the string values and used this irule

for example with the uri below:

iRule 1

when HTTP_REQUEST {
if { ( [class match [string tolower [HTTP::uri]] equals mt_envir_dg] ) } {
pool variable_pool
}else { pool normal_pool}}

We also tried the following irule

iRule 2 (Does not match)

when HTTP_REQUEST {
if { [HTTP::uri] contains "/A2ABC/" && ([HTTP::uri] contains "?02" || [HTTP::uri] contains "?05" || [HTTP::uri] contains "?env=02" || [HTTP::uri] contains "?env=05") } {pool variable_pool } else {pool normal_pool

Hello, this should do

when HTTP_REQUEST {
  if {[HTTP::path] starts_with "/A2ABC/" && [class match [HTTP::query]] eq query-data-group }{ pool variable_pool } 
}

I would suggest using a data-group for easier management and scalability on URI values, You'll need a string-type data group named "query-data-group" (to match my example) populated like this 

ltm data-group internal query-data-group {
    records {
        env=02 { }
        env=05 { }
    }
    type string
}

Thanks but when I create it as is I get syntax error. I think there may be a missing bracket but when I add it I still get a syntax error

[southern_shredd]

Will changing the order affect the logic much?  Its the only way that does not give a syntax error

when HTTP_REQUEST {
if { [class match [string tolower [HTTP::query]] equals query-data-group] && [HTTP::path] starts_with "/A2ABC/" } {
pool variable_pool }
else {
pool normal_pool
}
}
