$var(x) = “x” + y + z;

$hdr($var(x));

Hello,

I'm having an issue where this doesn't work:

#!trydef PRODUCT "Foo"

if( $hdr("X-" + PRODUCT + "-Transport") != "" ) {

    add_uri_param( $hdr("X-" + PRODUCT + "-Transport") );

}

It seems Kamailio doesn't like the concatenation within the $hdr(). Concatenation does work in other places though:

append_hf( "X-" + PRODUCT + "-Transport: tcp\r\n" );

Can anyone advise how to make the concatenation within $hdr() work? Thanking you in advance.
