Hi Ivan,

 

My questions is, I have already set maximum length Any to parameter "ctl00" but when I enable block mode for policy then an after again users are getting the WAF blocked error under the category of "Illegal Parameter Value Length" for same parameter.

 

How I can resolve this problem ? please advice.
