My domain is setup with free DNS hosting (allows refer to this as "Y"), however am only because of the url sending options of "301, 302, iframe or disabled" when attemping to show towards the items in another URL (allows refer to this as "Z") .

I'm attempting to have "Z"'s URL hidden when individuals visit "Y".

Basically 301/302, "Z" is displayed within the address bar. Basically iframe, "Y" is incorporated in the address bar, however viewing the origin shows "Z". Disabled clearly does nothing.

The DNS hosting doesn't give any option for example "cloaking", same with there anything I possibly could achieve this customers only begin to see the "Y" URL and do not realize that any submissions are originating from "Z"?
