Hi Splendid81,

you may use the iRule code below...

 

when HTTP_REQUEST { 
    if { [HTTP::header values ""] ne "" } then {
         HTTP::header remove ""
        HTTP::header replace "" [HTTP::header values ""]
    }
}

 

 

Note: You may uncomment the HTTP::header remove "" line if security is a concern for you. Otherwise LTM will just replace/add a single occourence without checking if the same header name exist more than once.

Cheers, Kai
