More Custom WAP Irules

It looks like you're closer...let's see if I can help a little.

You're going to want only one switch per header, otherwise you're going to run into issues, especially since you're using redirects and return statements. Try condensing these a bit, like:

when HTTP_REQUEST {
  switch -glob [HTTP::header User-Agent] {
    "*hiptop*" -
    "*AvantGo*" -
    "*Danger*" {
      HTTP::redirect "http://wap.vendor.com/partnergenericURL-D"
      return
    }
  }
  switch -glob [HTTP::header Accept] {
    "*vnd.wap.xhtml+xml*" -
    "*vnd.rim.html*" {
      HTTP::redirect "http://wap.vendor.com/partnergenericURL-C"
      return
    }
    "*vnd.wap.html*" {
      HTTP::redirect "http://wap.vendor.com/partnergenericURL-B"
      return
    }
    "*text/vnd.wap.wml*" {
      HTTP::redirect "http://wap.vendor.com/partnergenericURL-A"
      return
    }
  }
  if { [matchclass [string tolower [HTTP::uri] ] starts_with $::ot_recover] > 0 } {
    pool OLD_WEB_POOL
  } else {
    pool WEB_POOL
  }
}

That's a good first step in troubleshooting, anyway. If you still have problems, at least the logic will be a bit more condensed and you won't have to worry about the other switch statements not being evaluated.

HTH,
