Target transformed even when ignored via ctl: action

v2 master

When ignoring some targets, like a huge ARG, it's not matched but still transformed.
In some cases (several big ARGS), it can have dramatic impacts on performance.

Debug log showing the problem (ARGS:ParamToIgnore=a%2520b):

[9] fetch_target_exception: Found exception target list [ARGS:ParamToIgnore] for rule id 2000415
[9] fetch_target_exception: Target ARGS:ParamToIgnore will not be processed.
[4] Executing operator "rx" with param "a" against ARGS:ParamToIgnore skipped.
[9] T (0) urlDecode: "a b"

[9] T (0) lowercase: "a b"
[4] Rule returned 0.

Hi @marcstern ,

Can I assume that you're doing that exclusion via ctl:ruleEmoveTargetById (or other similar ctl action)? That same effect does not appear to occur if using SecRuleUpdateTargetById (etc.).

Correct, I use ctl:ruleRemoveTargetByTarget in this case
