Hello Akshay.

It's no possible to do it that way. You should differentiate each pattern.

switch -glob $useragent {
	"*havij*" {
		log local0. "Blocking this request due to detected user agent : *havij*"
		reject
	}
	"*zmeu*" {
		log local0. "Blocking this request due to detected user agent : *zmeu*"
		reject
	}
	"*sqlmap*" {
		log local0. "Blocking this request due to detected user agent : *sqlmap*"
		reject
	}
}

Regards,

Dario.
