Redirects to a mobile site not being completed by iRule

Your if is wrong, you really need a space after the Mozilla line, before the hyphen and the redirect line is in the wrong place. Here's my rewrite;

when HTTP_REQUEST {
 if { (([string tolower [HTTP::host]] equals "www.mcgill.ca") && ([string tolower [HTTP::uri]] equals "/desautels/programs/isp")) } {
  switch -glob [string tolower [HTTP::header User-Agent]] {
   "*blackberry*" -
   "Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_2 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8H7 Safari/6533.18.5*" -
   "*Android*" -
   "*Windows Phone OS*" { 
    HTTP::redirect "http://desautels.mobilizeme.com/undergraduate_programs/isp"
   }
  }
 }
}

Personally I'd use a Data Group and do it like this;

Create a Data Group (called user-agent-dg below) with just strings 
containing the user agent strings you wish to match

when HTTP_REQUEST {
 if { (([string tolower [HTTP::host]] equals "www.mcgill.ca") && ([string tolower [HTTP::uri]] equals "/desautels/programs/isp")) } {
  if { [class match [string tolower [HTTP::header User-Agent]] equals 
  user-agent-dg ] } { 
   HTTP::redirect "http://m.example.com" }
   Stop processing the iRule for this event here
   return
   }
}

I'd also suggest you do a quick search here on DC for some better lists of possible mobile User-Agent strings.

Hey thanks for the quick response, I will look at both examples and try them out. Happy New Year too everyone out there.

Hi I just tried this format, I am assuming the iRule should be using the & rather than ;amp However, i just get a page not found, rather than a redirect. when HTTP_REQUEST { if { (([string tolower [HTTP::host]] equals "www.mcgill.ca") & ([string tolower [HTTP::uri]] equals "/desautels/programs/isp")) } { switch -glob [string tolower [HTTP::header User-Agent]] { "*blackberry*" - "Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_2 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8H7 Safari/6533.18.5*" - "*Android*" - "*Windows Phone OS*" { HTTP::redirect "http://desautels.mobilizeme.com/undergraduate_programs/isp" } } } }

It's two &'s: &&. Any errors in the ltm log?

can you add some log command in the irule? traffic might not reach the HTTP::redirec command.

Thanks, that seems to get everything working properly, the only problem i still have is getting the right user-agent strings. When i use chrome as a Blackberry Bold, things are ok, but my iPHone or Android setting in Chrome don't seem to work. I tried looking up iphone user-agent string and plugged in *Apple-iPhone* but that does not seem to work at all. Chung

Hi chungyu,

 

 

I agree with Nitass. You should put a logging statement in your iRule and see what User-Agents are being processed.

 

 

log local0. "[HTTP::header User-Agent] Device Detected"

 

 

For Testing you can use a Mozilla Plugin User-Agent-Switcher.

 

 

A good place to get a list of User-Agents can be found here UserAgentString.com

 

 

Hope this helps.
