XDP doesn't load data if PDF is online

In Acrobat I can import/Export data off my LiveCycle form.

XDP file exported by Acrobat has the following lines:

     <pdf href="../myForm.pdf"/>

</xdp:xdp>

If load this file by Acrobat, is works perfectly (Opens the form and populates it). However, I need to have my PDF file on a server, so I edited the file:

     <pdf href="https://mysite.com/myForm.pdf"/>

</xdp:xdp>

Now when I open it in Acrobat Pro X,  it opens my web browser and loads the PDF but does not populate it.

Do you know what am I doing wrong? or is this another restricted feature?
