Thread:Project:Support desk/Upload a new PDF, but old PDF loading from Cache

Hello all,

I have a page on my Wiki that contains links to about 100 PDFs. When we make changes to any of the PDFs, a new version is automatically uploaded to the MediaWiki server, thus the page should always contain the latest available version of each PDF.

However, if a user has previously clicked on an older version of the PDF and the browser had cached the file, then when they click on the newer version of the PDF, the older version is opening from cache.

What workarounds do I have for this in MediaWiki? Obviously, I want the new version of the PDF to always open.

Many thanks,

Matt
