Help on a irule

Hello Everybody, i'm a newbie in irules and need some help in order to change an old irule to something simple and i'm don't know if i'm doing it right.

 

Original Irule ( when i put up on V11 i got a few error messages)

 

when HTTP_REQUEST { set url_var text([HTTP::host])

 

if { $url_var contains "sitea.test.com" } { HTTP::redirect "sitec.test.com/index" } if { $url_var contains "siteb.test.com" } { HTTP::redirect "http://test3.test.com/test" }

 

if { $url_var contains "sitec.test.com" } { HTTP::redirect "http://test3.test.com/login" } } }

 

I've tried to use the following irule but i'm getting errors anyway.

 

when HTTP_REQUEST { if {[string tolower [HTTP::host]] contains "sitea.test.com" { HTTP::redirect "http://sitec.test.com/index"} if {[string tolower [HTTP::host]] contains "siteb.test.com" { HTTP::redirect "http://test3.test.com/test"} if {[string tolower [HTTP::host]] contains "sitec.test.com" { HTTP::redirect "http://test3.test.com/login"}

 

Am i doing something wrong? Can someone point out the best way to do these redirects?

 

Thanks!

    when HTTP_REQUEST {
   if { [class match [string tolower [HTTP::host]] contains mysites] } {
     HTTP::redirect [class match -value [string tolower [HTTP::host]] contains mysites]
   }
}

    With string class "myclass" as follows

    Key              Value
sitea.test.com   http://sitec.test.com/index
siteb.test.com   http://test3.test.com/test
sitec.test.com   http://test3.test.com/login

      This gives you a simple iRule using data classes which means you can remove or add sites as you please and the iRule will automatically use them. The data class is always first match.

    Hi Amanda...thanks for the question! Are you using v11.4+ or are you on an older version (11.3 or older)? One reason I ask is that you can do these redirects using an HTTP Class profile (v11.3) or with a policy using the new Centralized Policy Matching (CPM) in version 11.4 and newer. You very likely won't even need an iRule! I can point you in the right direction based on the version you are using.

     

    Thanks! John

    Also, you can achieve all of this with HTTP Class profiles (up to v11.3) or HTTP Policies from v11.4+
