I am using 3rd party API that is making data available to us on a public URL. I want this data to be on my website without the user knowing the exact location from where the data is being fetched. 

Example: 
Data to be fetched from this URL: <https://example.com/1477116779.16443511_0.mp3>
Data to be displayed on this: www.zigsaw.in/telephonicinterviews/1477116779.16443511\_0.mp3

I tried using IFrames 

```
<iframe src="https://example.com/1477116779.16443511_0.mp3" width="100%" height="100%" frameborder="0" scrolling="no" />

```

but it allows for "open link in new tab" thus revealing the original page source

Background:We are a recruitment startup and do not want people out there know our little jugaad. Eventually, they would know but I would prefer a 3-4 months headstart.

P.S. : Downloading the data & uploading it on my server is also a solution but I would not want to unnecessary burden my hosting. Since these are audio files, it would take huge space.
