Any help appreciated. I’ve tried to find a solution and have only run across suggestions involving .htaccess files and some other things that I wish to avoid. I’m using Joe Workman’s awesome Total CMS for a site. I have a link (the class schedule link in the website below) that is fed by Total CMS’s “File” element. Whenever a file is uploaded to populate this link it has the same file name. As a result “old” PDF files are getting cached and the newly uploaded PDF’s are not displaying (sans a user refresh of their browser).

Any thoughts on how I could either stop the caching of this one particular link/file and/or automatically append the file name on upload so that the file name is different (thus avoiding the cache issue). I feel like I’m missing a simple solution here 😕

Thanks for the reads everyone. Though I was hoping to find a way within Total CMS and/or Rapidweaver I went ahead and dove into the .htaccess file route based on something I found on a PHP forum (link below for credit where credit is due). It was very straight forward and seems to have resolved the caching issue. Further…the site has not exploded yet 🙂

Here is the code I discovered at the link above. Hope this helps someone in some way.

/\</ FilesMatch “.(pdf)$”\>  
FileETag None  
  
Header unset ETag  
Header set Cache-Control “max-age=0, no-cache, no-store, must-revalidate”  
Header set Pragma “no-cache”  
Header set Expires “Wed, 11 Jan 1984 05:00:00 GMT”  
  
\</FilesMatch /\>/
