class match/data group - uri pool selection failing...

Hello,

 

 

I have an iRule that is giving me some trouble. I created a string datagroup of several URIs. The goal is just to look for a match on a particular URI and then send to the pool if a match is found. Otherwise, send the request to the landing page. The LTM is running 10.2.0 1707.15. For some reason, EVERY reqeust always goes to the landing page. A match is never found. The first line in the datagroup is another option I was trying. Any help would be very much appreciated.

 

 

when HTTP_REQUEST {

 

if { [class match [string tolower [HTTP::uri]] starts_with DMPS_URI_List] } {

 

pool DMPS_Stage_88

 

}

 

else {

 

HTTP::redirect "https://apps.company.com/"

 

}

 

}

 

 

class DMPS_URI_List {

 

{

 

"bpptasks" { "apps.company.com/bpptasks/" }

 

"dpptsks"

 

"jpptasks"

 

"lpptasks"

 

"gpptasks"

 

"mppatasks"

 

"opptasks"

 

}

 

}

 

 

 

Thank you,

    I've already tried that. I started out with a single leading slash but it made no difference so I began experiementing. I will remove the leading slashes right now though.

     

     

    Any more ideas?

    Can you update the class so it's like this: 

    class DMPS_URI_List {
   {
      "/bpptasks"
      "/dpptasks"
      "/jpptasks"
      "/lpptasks"
      "/mpptasks"
      "/opptasks"
   }
}

    And then use the logging in this iRule to test: 

    when HTTP_REQUEST {
   if {  [class match [string tolower [HTTP::uri]] starts_with DMPS_URI_List] } {
      pool DMPS_Stage_88
      log local0.info "Match found for [HTTP::uri] in [class get DMPS_URI_List]"
   } else {
      HTTP::redirect "https://apps.company.com/"
      log local0.info "NO Match found for [HTTP::uri] in [class get DMPS_URI_List]"
   }
}

    And post the debug logging from /var/log/ltm for a few requests which fail?
