    Is there anything else in the iRules? Or are they just a single event? Two iRules shoould both fire, one after tjhe other, unless the first has a discard, drop or event statement...

    Can you put a logline in the start of the event to indicate whether they're being called, and what the URI is

    (Oh. I'd probably re-write the iRules to do a lookup in a class rather than a whole lot of if/then/elseif's... It'll scale better. e.g. (I was going to write one, but the findclass wiki page has it as an example already) 

     
 class URIredirects { 
   "/dir1/dir2/dir3/ http://somehost.somewhere.com/redirect_target.html" 
   "/dir4/dir5/dir6/ http://someotherhost.nowhere.com/redirect_target.html" 
 } 
  
 when HTTP_REQUEST { 
   set location [findclass [HTTP::uri] $::URIredirects " "] 
   if { $location ne "" } 
     HTTP::redirect $location  
   } 
 }

    I'd guess this is an issue with trying to send a redirect from both rules on the same request. /var/log/ltm should show a runtime TCl error about multiple redirect invocations. For example, http://www.acbg.com/saleshub/ucc is going to match the first iRule check for a URI ending with /ucc and the second iRule check for /saleshub/ucc.

    Hamish's suggestion of using a datagroup and the findclass command is a good one if you don't need to use wildcards. If you do need to use wildcards, you could use a switch statement instead of a datagroup and findclass or the if/elseif/else chain. It would be idea if you could combine the iRules into one to ensure that only one redirect is attempted per HTTP request. 

     
 switch -glob [string tolower [HTTP::uri]] { 
    "*/saleshub/ucc" { 
       HTTP::redirect "https://microsite.accenture.com/ACBG_SalesHub/solutions/Pages/Outsourcing.aspx" 
    } 
    "*/ucc" { 
       HTTP::redirect "https://microsite.accenture.com/ACBG/Solutions/UCandC/Pages/default.aspx"  
    } 
    default { 
        Take some default action 
    } 
 }

    No matter what though, you'll need to pick which matches you want take priority for each URI stem (/saleshub/ucc or /ucc, etc).

    Hi Aaron/Hamish,

     

     

    Thanks for the reply.

     

     

    Getting the following error when trying to apply irule provided by Aaron

     

    01070151:3: Rule [Vanity-Sales] error:

    "*/ucc"

     

    { HTTP::redirect "https://microsite.accenture.com/ACBG/Solutions/UCandC/Pages/default.aspx" }

     

    }]

    Sorry, that was a code snippet. It would need to be in the HTTP_REQUEST event:

     

     

     
 when HTTP_REQUEST { 
  switch -glob [string tolower [HTTP::uri]] {  
     "*/saleshub/ucc" {  
        HTTP::redirect "https://microsite.accenture.com/ACBG_SalesHub/solutions/Pages/Outsourcing.aspx"  
     }  
     "*/ucc" {  
        HTTP::redirect "https://microsite.accenture.com/ACBG/Solutions/UCandC/Pages/default.aspx"   
     }  
     default {  
         Take some default action  
     }  
  }  
 }

    Just extend Aaron's example: 

      
  when HTTP_REQUEST {  
   switch -glob [string tolower [HTTP::uri]] {   
      "*/saleshub/ucc" {   
         HTTP::redirect "https://microsite.accenture.com/ACBG_SalesHub/solutions/Pages/Outsourcing.aspx"   
      } 
      "*/saleshub/cct" { 
         HTTP::redirect "https://microsite.accenture.com/ACBG_SalesHub/solutions/Pages/CCT.aspx" 
      } 
      "*/ucc" {   
         HTTP::redirect "https://microsite.accenture.com/ACBG/Solutions/UCandC/Pages/default.aspx"    
      }   
      "*/cct" { 
         HTTP::redirect "https://microsite.accenture.com/ACBG/Solutions/CustomerContact/Pages/default.aspx" 
      } 
      default {   
          Take some default action   
      }   
   }   
  }

    You just want to make sure your saleshub matches occur first in the switch so your matches occur correctly for /saleshub/*
