Newlines won't print in the log messages and the function you're looking for is called "join." I think the combination is what may be causing your issue here. Try printing them in an HTTP response like this and see how it works: 

ltm rule concat_http_headers {when HTTP_REQUEST {  set header_names [HTTP::header names]  foreach header $header_names {    lappend headers "$header: [HTTP::header value $header]"  }   HTTP::respond 200 content [join $headers "\n"]}}

Hope this helps,

George
