wsdlsoap:address generated by http component for proxied endpoint misses trailing slash

the wsdlsoap:address generated by a http component proxying an internal endpoint looks like:
http://localhost:8192/Service/VinciService
The http component intead expect calls for that web service at http://localhost:8192/Service/VinciService/
so the trailing slash is missing.
If the url without slash is used a http 302 code is returned, this can be automatically managed by some http clients.
