Replace an header authorization request with policy or iRule doesn't work ...

Hi all, I need to replace an header in request : the original header is "X-epsilon-Authorization" and the new header is "Authorization". I don't know if the value of header is necessary but is...

Try below. Modify the names of the header if needed. You can enable logging to see if it's replacing as expected.

when HTTP_REQUEST {
if { [HTTP::header exists "X-epsilon-Authorization"] } {
set value [HTTP::header value X-epsilon-Authorization]
HTTP::header remove X-epsilon-Authorization
HTTP::header insert Authorization $value
} else {
 return
 }
 foreach aHeader [HTTP::header names] {
  # log local0. "$aHeader: [HTTP::header value $aHeader]"
      }
}

Hi SanjayP,

Thanks for reply !

I try the irule but that return an error: "01070151:3: Rule [/Common/A_irule] error: /Common/A_irule:2: error: [parse error: PARSE syntax 33 {syntax error in expression " HTTP::header exists X-mafrenchbank-Authorization ": variable references require preceding $}][{ HTTP::header exists X-mafrenchbank-Authorization }]"

Thanks

It works !!

Just the hooks were missing [HTTP::header exists "X-epsilon-Authorization"]
The irule run perfectly and the value of Header has been changed.

Thanks a lot and have a good day !
