Fair enough.
If Adobe is not installed on the client, how will the server know that the PDF is not displayed. I have IIS, classis ASP in this case.
Here is the piece of code:
<form name="p" action="some.asp" method="post">
<%=embedSrc%>
<input type=button>
.
.
</form>
where embedSrc is:
<embed height=600 width=900 src="myPdf.pdf"></embed>
The src is taken from a db,
