fun with irule

I am working on an excersise to insert random quotes into http headers. I have an irule that uses data groups and if your subnet is in the DG a header with a specific quote is inserted, if your IP subnet is not specified your get a default quote. I found an irule to randomize a bunch of characters but cant figure out how to randomize quotes.

 

perhaps a DG of quotes and then somehow time the time/sec to pull out a random quote. what I am trying to do is find a command or irule that functions like the fortune command in linux.

    You can have a DG of quotes keyed by numbers, and then generate a random number as the key. If you have, say, 10 quotes, you can get a random number like this:

    expr {int(rand()*10)}

    .

    Slightly modified. You may try this:

     

    Code

    when HTTP_REQUEST {

     

    set random [ expr {int(rand()*2)}] log local0. "random = $random" set member [class match -value $random equals dg] log local0. "member = $member" }

     

    --

     

    dg integer type:

     

    0: quote0

     

    1: quote1
