Change port http File Upload plugin

I have my server configured so prebind goes to https//mysite/http-bind/ and apache with reverse proxy forwards it to https//mysite:7443/.
How can I configure http file upload plugin (or Openfire itself) so http uploads are sent to https://mysite/httpfileupload/… instead of https://mysite:7443/httpfileupload/… ?
I have problems with https certificate if requests are sent to port 7443.

Thanks.

The server binds to the port defined in the system property httpbind.port.secure - change that to 443 (or any value you like) and restart,
