irule redirect and switch -glob

Hey guys - trying to setup irule so we can redriect uri to servers.

how can i add the switch -glob in to this irules - or is there a better way of d0ing this?

Code when HTTP_REQUEST { 
if { [HTTP::uri] == "/filetransfer" } {
    pool mix_prod_v1_filetransfer
}
    elseif { [HTTP::uri] == "/view.net" } {
    pool mix_prod_v1_view
}
    elseif { [HTTP::uri] == "/webimagedownloader/" } {
    pool mix_prod_v1_webimage
}
else {
    pool mix2prod.test_pool
}

}

I gather you are trying to use partial matching with the -glob option. Try this...

when HTTP_REQUEST {
  switch -glob [string tolower [HTTP::uri]] {
    "/filetransfer*" { pool "mix_prod_v1_filetransfer" }
    "*/view.net" { pool "mix_prod_v1_view" }
    "*/webimagedownloader/*" { pool "mix_prod_v1_webimage" }
    default { pool "mix2prod.test_pool" }
  }
}

I've included all three type of pattern matching. Adjust as needed.

item* -- starts with item
*item -- ends with item
*item* -- contains item

Hi Daemien, Try the following

   when HTTP_REQUEST {
        switch -glob [string tolower [HTTP::uri]] {
          "/filetransfer" { 
                pool mix_prod_v1_filetransfer 
          }
          "/view.net" { 
                pool mix_prod_v1_view 
          }
          "/webimagedownloader/" {
                pool mix_prod_v1_webimage
          }
          default { 
                pool mix2prod.test_pool 
          }
         }
    }

I hope this helps

  Remember "-glob" switch allows the use of starts_with, ends_with, and contains. -=Bhattman=-

  I am not sure what you mean? Can you provide a brief example?

You can't do /Filetransfer or Filetransfer/ or Filetransfer. without the "-glob" statement in the switch command.

The following is great article about IF, ELSEIF, and Switch functions
