Irule Wildcard with excules

Hi !

 

I need an irule that will redirect to another url all request that contains _vti_bi but will exclude 2 url's :

 

/_/_vti_bin -> to redirect

 

/_/_vti_bin/client.svc/ProcessQuery -> dont do anything

 

/*/_vti_bin/sites.asmx ----> do not do anything

 

Thanks,

 

Aviv Hassidim

    Try this:

    when HTTP_REQUEST {
    if { [string tolower [HTTP::uri]] contains "_vti_bi" } {
      switch -glob [string tolower [HTTP::uri]] {
        "/_/_vti_bin/client.svc/ProcessQuery" {
            return
        }
        "/*/_vti_bin/sites.asmx" {
            return
        }
        default {
            HTTP::redirect "http://www.xyz.com"
        }
      }
    }
}

      First condition in the switch will never match. Remove the capital letters from the string: "/_/_vti_bin/client.svc/processquery"

    it seems okay here.

    e.g.

     config

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:80
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        tcp { }
    }
    rules {
        qux
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 41
}
root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  if { [HTTP::uri] contains "_vti_bi" } {
    switch -glob [HTTP::uri] {
      "/_/_vti_bin/client.svc/ProcessQuery" {
        return
      }
      "/*/_vti_bin/sites.asmx" {
        return
      }
      default {
        HTTP::redirect "http://www.xyz.com"
      }
    }
  }
}
}
