Our company website contains some static PDF file. These PDF files will be replaced quarterly with the same filename.
Users found that the PDF content remain unchanged. IT support told them to clear the IE cache (internet options -> Browsing history -> delete -> all checked) and download the PDF file but the file still the same.
We opened the "Temporary internet Files" folder, we have found that the PDF file is still there after the delete.
Therefore, we select all the files and press delete button. The file is now "real" deleted. The users can read the updated PDF files.
What's going on? Why this happens? Is it a IE bug? Please suggest.
Thank you very much.
