HTTP Cookie Redirect based upon cookie value and URL

Hi Guys,

Have an internal APP with needs language support now... Basically , redirect to a different URL based upon a language cookie set on the web server and the URL asked for .

The below is basically pretty wrong , and help really grateful , had a good search through the forums but can't find that much which is in the direction I need.

when HTTP_REQUEST {

 Try to select a pool based on the http cookie containing pool information

if { [HTTP::cookie exists "LANG"] and [HTTP::cookie value "LANG"] contains "EN"} {
xxxx(and website is www.website.com or website.com (the root "/") then redirect to --->www.website.com/page.apsx?lang=en)
}
elseif { [HTTP::cookie exists "LANG"] and [HTTP::cookie value "LANG"] contains "ES"} {
xxxx(and website is www.website.com or website.com (the root "/") then redirect to --->www.website.com/page.apsx?lang=ES)
}
elseif { [HTTP::cookie exists "LANG"] and [HTTP::cookie value "LANG"] contains "DE"} {
xxxx(and website is www.website.com or website.com (the root "/") then redirect to --->www.website.com/page.apsx?lang=DE)
}
else {
(no nothing)
}
}

Many Thanks Neil

    Try this Neil, no expert at iRules but enjoy giving them a go and happy to help if I can.

    when HTTP_REQUEST {
if { [HTTP::cookie exists "LANG"] } {
  switch [HTTP::host] {
    "www.website.com" -
    "website.com" {
       switch [HTTP::cookie value "LANG"] {
       EN { HTTP::redirect "www.website.com/page.apsx?lang=en" }
       ES { HTTP::redirect "www.website.com/page.apsx?lang=ES" }
       DE { HTTP::redirect "www.website.com/page.apsx?lang=DE" }
      }
    }
   }
  }
}

    Hi Nathan ,

    Thanks for the reply.

    The HTTP cookie part works perfectly , the redirection works. However it appears to fail as the rule applies to any URI , eg www.website.com/test/page it will redirect to "www.website.com/page.apsx?lang=en" , so you can't browse to any page deeper....

    I tried the HTTP:HOST equals - but that doesn't appear to work. The request should only fire when for the root page....

    when HTTP_REQUEST {
if { [HTTP::cookie exists "LANG"] } {
  switch [HTTP::host] equals {
    "www.website.com" -
    "website.com" {
       switch [HTTP::cookie value "LANG"] {
       EN { HTTP::redirect "www.website.com/page.apsx?lang=en" }
       ES { HTTP::redirect "www.website.com/page.apsx?lang=ES" }
       DE { HTTP::redirect "www.website.com/page.apsx?lang=DE" }
      }
    }
   }
  }
}

    Neil, give this a shot

    when HTTP_REQUEST {
if { [HTTP::cookie exists "LANG"] } {
  switch "[HTTP::host][HTTP::uri]" {
    "www.website.com/" -
    "website.com/" {
       switch [HTTP::cookie value "LANG"] {
       EN { HTTP::redirect "www.website.com/page.apsx?lang=en" }
       ES { HTTP::redirect "www.website.com/page.apsx?lang=ES" }
       DE { HTTP::redirect "www.website.com/page.apsx?lang=DE" }
      }
    }
   }
  }
}

    This will only work for URI's of "/" though. If you want to include a index.html (or similar default page for your system), you'll have to add different values to the comparisons for each host like "www.website.com/index.html".
