irule to append www to each page

when HTTP_REQUEST {

  if { [string tolower [HTTP::host]] eq "webpage.com") }{
    HTTP::respond 301 Location "http://www.webpage.com[HTTP::uri]" Connection Close
  }

}

Hi,

You can use an irule to detect if www is present and append it if not present :

when HTTP_REQUEST {
    if { !([HTTP::host] contains "www.") } {
        HTTP::host "www.[HTTP::host]"
    }
}

Something like this:

when HTTP_REQUEST {

  if { [string tolower [HTTP::host]] eq "webpage.com" }{
    HTTP::respond 301 Location "http://www.webpage.com[HTTP::uri]" Connection Close
  }

}

Ha, that was quick. Thanks for that. Just one more thing....

I have some sub domains hitting that VS. IE. http://sub.webpage.com will the rule mean that www will be appended to the subdomain?

Thanks

Tom.

Great, Thanks for all your help.

Tom.

when HTTP_REQUEST {
    if { ! [HTTP::host] starts_with "www" } {
        HTTP::redirect http://www.[getfield [HTTP::host] ":" 1][HTTP::uri]
    }
}

Nice and all purpose...
