SYMPTOM

 

When viewing PDF files using AttachView and clicking on pages that have not been rendered in the initial view, users may receive the following error message:

 

“Page cannot be displayed”

 

CAUSE

 

AttachView creates “\” in the URL after the initial rendered pages for a PDF file are displayed.

 

This behaviour occurs when ISA server is configured to block non-standard HTTP characters and it blocks backslash in the URL as it is a non-standard HTTP character.
