### Description

I see that when the xhttp module is enabled, kamailio will forge the Via header to process the HTTP request, but the parse sip error will be generated in the log
```
104(113) ERROR: <core> [core/parser/parse_uri.c:1417]: _parse_ruri(): bad uri </metrics>
104(113) ERROR: <core> [core/parser/parse_uri.c:1455]: parse_orig_ruri(): parse orig ruri failed
104(113) ERROR: pv [pv_core.c:355]: pv_get_ouri_attr(): failed to parse the R-URI
```

### Troubleshooting


#### Debugging Data

Set up a Kamailio server with the xhttp module enabled.

```
loadmodule "xhttp.so"

event_route[xhttp:request] {
$var(xhttp_prom_root) = $(hu{s.substr,0,8});
if ($var(xhttp_prom_root) == "/metrics") {
xlogl("L_INFO", " [$utimef(20%y-%d-%m %H:%M:%S)] [$(hdr(Call-ID))]: [bizCall=$xavu(bizCallId)] [bot=$xavu(bizBotId)] Called metrics\n");
prom_dispatch();
}
}
```
