auto refresh a link to pdf file

[Dave]

Using asp.net - is there a way to have a link to a pdf.file - that will auto
refresh the pdf file before it opens.

Thanks

Hi Dave,

As for the refreshing the file on serverside before a hyperlink is clicked,
there hasn't any convenient means to do so as far as I know. Because the
file is on the serverside which need to use serverside code to manipulate ,
however the hyperlink click event is at clientside.

My suggestion is that you do not directly expose the files on the server
via hyperlinks to user. You can use serverside code to write the file
stream into the asp.net web page's response stream so as to perform the
same function. Also, we can even store the files in database and retrieve
them as binary data from database and write down to page's response stream.
Here are some tech articles and former threads discussing on this:
