Will go bit different way to solve issue. It will be easy to add more url in datagroup

class

. Lets try and update if working.

class host_url {
    access.testxyz45.com
    abc.testxyz45.com
    def.testxyz45.com
    mail.testxyz45.com  
    }

    when HTTP_REQUEST {
       if { [matchclass [string tolower [HTTP::host]] equals host_url] } {
       persist source_addr 255.255.255.255 600
         persist source_addr [] [] -- DevCentral Syntax
       Link : https://devcentral.f5.com/wiki/iRules.persist.ashx
    }
}

I will request user to click iRule which working and solving issue. So that other can be refer.

Hi F5_Rock,

Thank you for providing the iRule, Can we use a Switch Statement instead of an If stmt.

===========

class host_url {

access.testxyz45.com abc.testxyz45.com def.testxyz45.com mail.testxyz45.com }

when HTTP_REQUEST {

switch -glob -[string tolower [HTTP::host]] { host_url { persist source_addr 255.255.255.255 600 } }

}

Thanks,

Yugandhar.

Syntax is different for switch statement. @youssef has already provided switch iRule. Refer his iRule n let us know if any issue.

Thank you .. I thought 'host_url' will be replaced with the values specified in the Data Group...So we can't refer a Data Group in the Switch Statement :)

Thank you F5_Rock, I tested the if stmt with matchclass and switch statement & both worked.

Check the iRule which is correct. It will be helpful for others.
