HTTP::header User-Agent question

I have an irule for we are setting up for featured mobile phones and smart phones.

 

1 data class list many different codes, for example nokia, the non-smartphones.

 

The other data class just lists smartphones we support.

 

The goal is to detect a smartphone and direct it to one site and if it's a featured phone it detects it and directs it.

 

The problem is, if I use just a PC browser it always seems to take the featured phone path.

 

If it's just a standard browser on a pc, is there a way to force it to use it.

 

Seems like the HTTP::header User-Agent is looking into my data class with all the codes and then uses the wap data class regardless. I would think if I am using a not in my "if" it should use the set of normal?

 

All

 

 

 

Below is the irule

 

when HTTP_REQUEST {

 

set wap https://wapsite.com/uri

 

set normal https://normal.com/uri

 

set smart https://smartphonesite.com/uri

 

if { [HTTP::host] equals "https://mysite..com" } {

 

if { not [class match -- [string tolower [HTTP::header User-Agent]] contains user_agent_tokens_class] }{

 

log local0. "Normal web site"

 

HTTP::redirect $normal

 

}

 

} else {

 

if { [class match -- [string tolower [HTTP::header User-Agent]] contains user_agent_tokens_class] }{

 

log local0. "wap phone"

 

HTTP::redirect $wap

 

if {[class match [string tolower [HTTP::header User-Agent]] contains mobile_device_providers]}{

 

log local0. "smart phone"

 

HTTP::redirect $smart

 

event disable

 

do nothing

 

} else {

 

}

 

}

 

}

 

}

    Hey,

     

    Initial observation, try removing the https:// from http host i.e. just mysite.com.

     

     

    Hope this helps,

    I'd also take a closer look at your if else clauses, looks like you'd have better luck with if/elseif/else combination.

    Try this; 

    
when HTTP_REQUEST {
set wap https://wapsite.com/uri
set normal https://normal.com/uri
set smart https://smartphonesite.com/uri

 if { [HTTP::host] equals "https://mysite..com" } {
  if { [class match -- [string tolower [HTTP::header User-Agent]] contains user_agent_tokens_class] }{
    log local0. "wap phone"
    HTTP::redirect $wap
    return }
  elseif {[class match [string tolower [HTTP::header User-Agent]] contains mobile_device_providers] } {
    log local0. "smart phone"
    HTTP::redirect $smart
    return }
  else {
   log local0. "Normal web site"
   HTTP::redirect $normal
   }
}
}

    as nathan mentioned, i just removed "https://" from Steve's irule. additionally, since you do string tolower twice, you had better save it to variable and re-use it. 

    when HTTP_REQUEST {
   set wap "https://wapsite.com/uri"
   set normal "https://normal.com/uri"
   set smart "https://smartphonesite.com/uri"

   if { [HTTP::host] equals "mysite.com" } {
      set user_agent [string tolower [HTTP::header User-Agent]]
      if { [class match -- $user_agent contains user_agent_tokens_class] } {
         log local0. "wap phone"
         HTTP::redirect $wap
      } elseif { [class match -- $user_agent contains mobile_device_providers] } {
         log local0. "smart phone"
         HTTP::redirect $smart
      } else {
         log local0. "Normal web site"
         HTTP::redirect $normal
      }
   }
}
