Locate and use URL for pdf file on SAS server

[MichaelTab]

Hi, 

I have been trying to connect an image as a button link to PDF file. The file is located on the SAS server itself. 

I used the URL from the Chrome adress line and placed the address in the Image>Actions>Url Links. 

It works till the first reload of the browser. After the reload, pressing on the image results a message "ERR_FILE_NOT_FOUND"

Please advise the right way to get the URL to the file. 

Thank You. 

Michael
