xdmp:get-request-header("X-Forwarded-For") ought to do it (if the HTTP server
is
creating a header with just that spelling; that's what Apache does).
We have a function we use to determine the actual source IP address that you
might be able to use or adapt:
(:~
: Ascertain IP address masked by Apache rewrites.
:
: @return The actual client address.
:)
declare function user:get-actual-client-address() as xs:string {
let $apparentIP := xdmp:get-request-client-address()
let $forwardedFrom := xdmp:get-request-header("X-Forwarded-For")
return
if ((exists($forwardedFrom)) and ($apparentIP eq '127.0.0.1'))
then tokenize($forwardedFrom, ', ')[last()]
else $apparentIP
};
