set string to lower case not working for query

i understand HTTP::query does not set/change query part.

HTTP::query

so, can you try to set HTTP::uri to lowercase to variable and use it in comparision later?

e.g.

[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
  log local0. "0: [HTTP::uri]"
  set uri [string tolower [HTTP::uri]]
  log local0. "1: $uri"
}
}

[root@ve10:Active] config  tail -f /var/log/ltm
Jul 11 14:54:20 local/tmm info tmm[4950]: Rule myrule : 0: /test?ABC=1234
Jul 11 14:54:20 local/tmm info tmm[4950]: Rule myrule : 1: /test?abc=1234

just in case if you have not yet seen this note.

Notes

Beginning in version 11, the cached behavior changes so that the value of the uri is updated immediately after being set. Previously, you would need to log the value in a higher priority (read: higher number) of the current event or log the value in a later event in order to reflect the change.HTTP::uri
