    Hi you need to use {} to enclose your regex instead of "". Also for the iRule try this;-

    if { [HTTP::header User-Agent] matches_regex {(Android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|Android|iP(hone|od|ad)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino}} { 
     It's a mobile device
    if {[HTTP::uri] eq "/?fr=mb"} {
        HTTP::redirect "http://www.mydomain.com/" 
    } else {
        HTTP::redirect "http://m.mydomain.com/" 
    }
}

    Hi you just need to add some loggin to work out why it's not matching as you expect. I've just show a fragment below to show where to log;-

    if {[HTTP::uri] eq "/?fr=mb"} {
    log local0. "Redirecting [HTTP::uri] to http://www.settour.com.tw/"
    HTTP::redirect "http://www.settour.com.tw/" 
} else {
    log local0. "Redirecting [HTTP::uri] to http://m.settour.com.tw/"
    HTTP::redirect "http://m.settour.com.tw/" 
}

    Then you have to check the logs in /var/log/ltm - you should quickly figure out where you are going wrong.

    Hello Stephen,

    You can try below iRule, I have same kind of requirement and the below iRule is working fine.

    when HTTP_REQUEST { set uri [string tolower [HTTP::uri] ]

    set mobile_site "http://m.mydomain.com"

    set full_site "http://www.mydomain.com"

            switch -glob [string tolower [HTTP::header User-Agent]] {

            "*iphone*" -
            "*android*" -
            "*windows phone*" -
            "*windows ce*" -
            "*bada*" -
            "*bb10*" -
            "*blackberry*" -
            "*symbinos*" -
            "*symbain os*" -
            "*symbian*" -
            "*java*" -
            "*winowsphone*" -
            "*windowsce*" {
                    HTTP::redirect "http://m.mydomain.com"
                return
                }

            }

    }

    Regards, Ashish.

    Hi Ashish,

     

    there may be a typo in "winowsphone", no ?

     

    Thanks, Pascal.
