link to pdf document in WP site

I would like to enter a hyperlink in a page or post in my WP website that takes the visitor to a site (or …?) where the visitor can see, read and print the pdf version of a document, but when the visitor is done and closes the page, or clicks on the go back arrow, the visitor comes back to my site. In other words, I do not want the visitor who has chosen to click on the link I provided to go outside my website after he/she is done with the document. Is this possible? I have now in my site 2 such links but, when the visitor closes the page holding the document, the visitor does not automatically come back to my site. You may click on

and click on the second or third links from top to bottom.
