We occasionally get reports from customers that they are unable to view our manuals, technical specs, or other documentation which we provide in Adobe's .pdf file format. Most frequently, customers describe a blank screen (or white screen or nothing happening) when they attempt to open one of our PDFs.
While there can be several reasons why things aren't happening as they should, more often than not the problem occurs for customers who are using Microsoft Internet Explorer 5 or greater on Windows and who view PDF files directly within the browser.
Why: There is a known problem with Internet Explorer opening PDFs within the browser when the URL (address) of the PDF file exceeds a certain length. This behavior can occur on any site (not just ours) if the URL is long enough. Our URLs can be rather long (a typical AutomationDirect URL looks like "http://cdn.automationdirect.com/static/manuals/d4anlg/d4anlg.pdf"). Though software vendors have released patches which are supposed to fix this behavior, our experience shows that the problem persists in many cases.
We know of a few workarounds.
Our recommended fixes (in order of convenience to you and effectiveness):
