Data Group List use in a switch

if [HTTP::uri] contains allowed_urls

 

set value "allowed"

 

}

 

 

I just want to know if the syntax is correct for the call to the data group list. Im assuming i only need to define the list in the data list group tab and not in the code.

 

 

Thanks

You can use the class command to look up the URI to see if it's in the datagroup like Colin's example:

when HTTP_REQUEST {

   set action [class match -value [string tolower [HTTP::path]] equals allowed_urls]
   if {$action ne ""}
       do stuff
  }
}

Hi Aaron

 

 

Colins example doesnt compile:

 

 

line 3: [undefined procedure: class] [class match -value [string tolower [HTTP::path]] equals blocked_list]

 

line 4: [missing a script after "if"] []

 

line 7: [command is not valid in the current scope] [}]

 

 

I don't want to define the list in the code but in the Data Group List tab (in the GUI under Local Traffic >> iRules >> Data Group List). Is this why its not updating?

 

 

Looking a again at Colins example, i want the same action to be performed for all strings in the Data Group List so i dont need to define the action until its found that the any of the strings in the list are in the url.

 

 

when HTTP_REQUEST {

 

 

set action [class match -value [string tolower [HTTP::path]] equals Portal_blocker_list]

 

if {$action ne ""}

 

do stuff

 

else set value "found"

 

}

 

}

 

The datagroup is always defined outside the iRule. You cannot define a datagroup within an iRule.

Which LTM version are you running? The class command was added in 10.0.0. If you're on v9.4.4, you can use this instead:

when HTTP_REQUEST {

   if {[matchclass [string tolower [HTTP::path]] equals allowed_urls]}
       do stuff
  }
}

For pre-9.4.4 add a $:: prefix to the datagroup name reference in the iRule.

using 9.4.8

 

 

when HTTP_REQUEST {

 

 

if {[matchclass [string tolower [HTTP::path]] equals blocker_list]}

 

do stuff

 

}

 

 

gives:

 

 

line 3: [missing a script after "if"] []

 

 

whats missing?

 

 

Thanks

can u try this?

 

 

when HTTP_REQUEST {

 

if {[matchclass [string tolower [HTTP::path]] equals $::blocker_list]} {

 

do stuff

 

}

Thanks nitass

 

 

That updates if i add another } at the end.

oh yes, i missed the last }.

That all works fine apart from the contents of the lists.

 

 

I noticed that if 72D0C6D25 is in the list that it doesn't recognize it in the uri for the irule to pick it up. Which is strange as numbers and letters are ok if they are separately defined in a list but together it doesn't recognize them. Which list type should alphanumeric be included in and what is the size limit of the individual list types? Can they have special characters also?

 

 

Thanks

i think its the upper case letters it doesnt like as abc12-d34ef-ghj-kjn-fds is fine. Does anyone know what the number of values can be in a data group list?
