Create 2 different iRules for Redirection

I think you could get away with doing something much simpler. For example, let's say you have a data group filled with domain names.

ltm data-group internal domlist {
    records {
        herownwork.com { }
        hisownwork.com { }
        myownwork.com { }
        thatownwork.com { }
        thisownwork.com { }
    }
    type string
}

Then the iRule might look something like this:

when HTTP_REQUEST {
    if { not ( [string tolower [HTTP::host]] starts_with "www." ) } {
        if { [class match [string tolower [HTTP::host]] equals domlist] } {
             host in the list - issue redirect to parent URL
            HTTP::redirect "http://www.yourwork.com"
        } else {
             host not in data group - redirect to self and add www.
            HTTP::redirect "http://www.[HTTP::host][HTTP::uri]"
        }
    }
}

Hi Kevin

Thanks a lot for the update , but in iRule1 there is one domain for which "www" is not at all required eg: workplace.yourwork.com , kindly suggest how to accommodate it in the same iRule as you mentioned above .

Hi Kevin

Thanks a lot and the above irule works fine !! However there is one issue :

--> myownwork.com gets redirected to http://www.yourwork.com

(myownwork.com is listed under Data group list)

--> www.myownwork.com doesnot gets redirected to http://www.yourwork.com and opens up as itself (www.myownwork.com)

Please suggest what could be done so that on browsing myownwork.com OR www.myownwork.com , it redirects to http://www.yourwork.com

Hi Experts

Can anyone please assist on this ?

Perhaps this:

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] ends_with "myownwork.com" } {
        HTTP::redirect "http://www.yourwork.com"
    } elseif { not ( [string tolower [HTTP::host]] starts_with "www." ) } {
        if { [class match [string tolower [HTTP::host]] equals domlist] } {
             host in the list - issue redirect to parent URL
            HTTP::redirect "http://www.yourwork.com"
        } else {
             host not in data group - redirect to self and add www.
            HTTP::redirect "http://www.[HTTP::host][HTTP::uri]"
        }
    }
}

Hi Kevin

The above doesnot work as per my requirement . I will give a quick recap again . Any URL falling under data group whether with "www" or without "www" should get redirected to parent URL http://www.yourwork.com . But any Other URL (not falling under data group and NOT starting with www , as well as not beginning with "myworkplace") should have just "www" append at the begining of the URL

I have modified your previous iRule as follows , please check this if it makes sense and also help in correcting the syntax :

when HTTP_REQUEST {

if { [string tolower [HTTP::host]] starts_with "www." } {
   if { [class match [string tolower [HTTP::host]] equals domlist] } {
         host in DG list but user types full URL www.myownwork.com - issue redirect to parent URL
        HTTP::redirect "http://www.yourwork.com"
} elseif { not ( [string tolower [HTTP::host]] starts_with "www." and not ([string tolower[HTTP::host]] starts_with "myworkplace") } {
    if { [class match [string tolower [HTTP::host]] equals domlist] } {
         host in DG list but user doesnt type full URL myownwork.com - issue redirect to parent URL
        HTTP::redirect "http://www.yourwork.com"
    } else {
         host not in data group - redirect to self and add www.
        HTTP::redirect "http://www.[HTTP::host][HTTP::uri]"
    }
}

}

Hi Kevin,

Kindly suggest on my query

Thanks and Regards, Ankur

Okay, this should be closer to your description:

when HTTP_REQUEST {
    if { [class match [string tolower [HTTP::host]] ends_with my_uri_dg] } {
         in the data group
        HTTP::respond 302 Location "http://www.yourwork.com"
    } else {
         not in the data group
        if { not ( [string tolower [HTTP::host]] starts_with "www." ) and not ( [string tolower [HTTP::host]] starts_with "myworkplace" ) } {
             not in datagroup, not start with www and not start with myworkplace
            HTTP::redirect "http://www.[HTTP::host][HTTP::uri]"
        } else {
             doesn't match any conditions
            return
        }
    }
}
