redirect Server side with no header User-Agent

Hello, I would like to create a rule that redirect only requests with no "User-Agent" I have a rule now that redirect Pc browsers and a switch in the rule that redirect mobile agents. I need another option incase the request come from the application side on the server which is not configured with header User-Agent.

 

thanks in advance, Shlomi.

    Something like this:

    when HTTP_REQUEST {
    if ( not ( [HTTP::header exists User-Agent] ) } {
         .. do something here ..
    }
}

    You might try "" as one of the switch conditions, but I haven't tested that. This should work though:

    when HTTP_REQUEST {
    if ( not ( [HTTP::header exists User-Agent] ) } {
        HTTP::redirect "http://mywebsite/[HTTP::uri]"
    } else {
        switch -glob [string tolower [HTTP::header User-Agent]] {
            "*blackberry*" -
            "*ipad*" -
            "*iphone*" -
            "*ipod*" {
                return
            }
            default {
                HTTP::redirect "http://mywebsite/[HTTP::uri]"
            }
        }
    }
}
