WampServer

Hi,

I have an intranet which is developed in WAMP server.
I want to hide pdf toolbar for a specific pdf's when it is opened in the web browser.

When am using like this;
<a href="\ex\example.pdf#toolbar=0">Click here</a>

This link works fine for first time is opened, but when i open in second time onwards, it is showing the toolbar again for that pdf.

Any idea/suggestions to solve this problem,

Thanking you...
