Hello Battman,

 

 

No luck still its giving me error.

 

I doubt that its becuase of class

 

I removed the class option and tried still i am getting error.

 

Please help

I think there is an extra brace at the end of the code

 

 

 
 when HTTP_REQUEST  {   
     if {[IP::addr[IP::client_addr] equals 10.1.1.1] } {   
 if { [matchclass [string tolower [HTTP::uri]] contains $::eligibility] } {   
         pool POOL_230_2   
         } else {   
        pool POOL_230_1   
     }   
      } elseif {[IP::add [IP::client_addr] eq 10.1.1.8] } {   
            pool POOL_230_ALL   
      } else {   
             switch [HTTP::method] {   
               "GET" { log local0. "GET method used" }   
               "POST" { log local0. "POST method used"}   
               default { log local0. "Unexpected method used" }   
             }   
             if { [matchclass [string tolower [HTTP::uri]] contains $::eligibility ]} {   
                 pool POOL_230_2   
        log local0. "Eligibility request made."   
 } elseif { [matchclass [string tolower [HTTP::uri]] ends_with $::images ]} {   
      pool POOL_230_ALL   
      log local0. "Image request Made"   
 } else {  
             pool pool_230_1   
      log local0. "Generic Request Made"   
 }   
       }   
     } 
 

 

 

 

I hope this helps

Hello Battman,

 

 

I am getting the following error

 

 

line 1: [undefined procedure: class] [class eligibility

 

line 24: [braces are required around the expression] [when HTTP_REQUEST {

 

line 51: [command is not valid in the current scope] [}]

 

 

Please help

Hi Sumod,

You are on the right track of how to define a class on the F5.

Here is what the class would look like on the configuration file where the class is a string.

 
 class eligibility {  
   "/fauxpro" 
   "/fauxpro/false/"  
  }

Hi Battman,

 

 

I just checked the Class MemberEligibility configuration and found as....

 

 

Class MemberEligibility > ClassType: String > class members > /fauxpro (and somemore with /fauxpro/false etc etc)

 

 

Could you please help me in converting the rule exactly according to this

Duh....I forgot about "contains one of operator" is for classes.

 

 

Then the code would be re-written as

 

 

 
 class eligibility { 
  "somethingsomething" 
 } 
  
 class images { 
    ".jpg" 
    ".gif" 
  } 
  
  
  when HTTP_REQUEST  {  
      if {[IP::addr[IP::client_addr] equals 10.1.1.1] } {  
  if { [matchclass [string tolower [HTTP::uri]] contains $::eligibility] } {  
                    pool POOL_230_2  
               } else {  
        pool POOL_230_1  
  }  
       } elseif {[IP::add [IP::client_addr] eq 10.1.1.8] } {  
             pool POOL_230_ALL  
       } else {  
              switch [HTTP::method] {  
                "GET" { log local0. "GET method used" }  
                "POST" { log local0. "POST method used"}  
                default { log local0. "Unexpected method used" }  
              }  
              if { [matchclass [string tolower [HTTP::uri]] contains $::eligibility ]}  {  
                        pool POOL_230_2  
         log local0. "Eligibility request made."  
  }  elseif { [matchclass [string tolower [HTTP::uri]] ends_with $::images ]}  {  
       pool POOL_230_ALL  
       log local0. "Image request Made"  
  } else { 
               pool pool_230_1  
       log local0. "Generic Request Made"  
  }  
        }  
      }  
  }  
 

 

 

I hope this helps

I dont think so...because when i checked in Classes option i had found an entry "MemberEligibility" "String" some URL's mentioned over there.

 

In 9.x how we will do it in the same way.

 

Please help me with this

 

Hi Sumod,

 

I suppose it would look more or less something like this untested code

 

 

 
 when HTTP_REQUEST  { 
     if {[IP::addr[IP::client_addr] equals 10.1.1.1] } { 
 if { [string tolower [HTTP::uri]] contains "memberelegibility" } { 
                   pool POOL_230_2 
              } else { 
       pool POOL_230_1 
 } 
      } else if {[IP::add [IP::client_addr] eq 10.1.1.8] } { 
            pool POOL_230_ALL 
      } else { 
             switch [HTTP::method] { 
               "GET" { log local0. "GET method used" } 
               "POST" { log local0. "POST method used"} 
               default { log local0. "Unexpected method used" } 
             } 
             switch [string tolower [HTTP::uri]] { 
                "*membereligibility* {  
                       pool POOL_230_2 
 log local0. "Eligibility request made." 
 } 
  "*images" { 
 pool POOL_230_ALL 
 log local0. "Image request Made" 
 } 
 default { 
 pool pool_230_1 
 log local0. "Generic Request Made" 
 } 
 } 
      } 
 } 
 

 

 

I hope this helps
