you might also want to try the $hdr PV :
xlog("L_INFO", "Via 0 host: $(hdr(Via)[0]{param.value,branch})\n");
if ($(hdr(Via)[1]) != $null) {
xlog("L_INFO", "Via 1 received IP: $(hdr(Via)[1]{param.value,branch}
)\n");
}
# Access the last Via header
if ($(hdr(Via)[-1]) != $null) {
xlog("L_INFO", "Last Via header branch:
$(hdr(Via)[-1]{param.value,branch})\n");
}
I'm writing the code by heart, didn't tested it, but I think this works
too!
