Websphere data group irule

I am in the process of implementing Websphere. There is an irule requirement that lists uris. Rather than list them specifically in the irule, I want to call them in a data group. I haven't been able to figure out how to appropriately call the dg though.

 

Here is the irule which is working without a dg.

 

when HTTP_REQUEST { switch -glob [string tolower [HTTP::uri]] { "/a/" - "/b/" - "/c/*" { pool WEBSPHERE_POOL_9086 } default { HTTP::respond 200 content { Wrong URL } } } }

    I just implemented something similar to the following:

    if {[class match [HTTP::uri] starts_with URL-DataGroup]} {
  pool WEBSPHERE_POOL_9086
} else }
  HTTP::respond 200 content { Wrong URL }
}

    I have tried the following; but get the TCL error when the rule is hit and am unable to access the site at all

    01220001:3: TCL error: /Common/WEBSPHERETEST2 - invalid command name "}" while executing "}"

    when HTTP_REQUEST {
switch -glob [string tolower [HTTP::uri]] if{[class match [HTTP::uri] starts_with URL_DATAGROUP]
{
pool WEBSPHERE_POOL_9086
}
else {
HTTP::respond 200 content {
Wrong URL
     }
    }
 }
}

    Why are you trying to use a switch statement? The Datagroup is essentially an externalized switch. Did you try the syntax as I wrote originally? I'm not sure if it works for your case exactly.

    The switch statement was in the Websphere deployment guide. I had removed almost everything in the rule and it still wasn't working with what is below

    when HTTP_REQUEST {
if{[class match [string tolower [HTTP::uri]] starts_with URL_DATAGROUP]
{
pool WEBSPHERE_POOL_9086
  }
 }
}

      one issue i see - you're missing a } after DATAGROUP ], and there's an extra } at the end - should look like: when HTTP_REQUEST { if{[class match [string tolower [HTTP::uri]] starts_with URL_DATAGROUP]}{ pool WEBSPHERE_POOL_9086 } }
