Log matched/detected pattern in switch statement.

I have been trying to write a security iRule for my organization that provides a basic security. Here is my code snippet where I am matching the useragent value with the provided patterns.

 

switch -glob $useragent {

"*havij*" -

"*zmeu*" -

"*sqlmap*" {

 

            log local0. "Blocking this request due to detected user agent : "

 

reject

}

}

 

How do I print the detected pattern here? If I try to print the $useragent, I will be logging the entire useragent value instead of only the detected pattern. Any help would be greatly appreciated.

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 } }
