Force Browser to use updated pdf file instead of cache version

[Blikkies]

Hey Guys, I have run into a small problem, we have sent a bulk email containing a link to a pdf file, a week after the bulk mail the pdf file had to be updated. My problem now is some of the recipients still viewing the cache version of the pdf, is there a way to force the browser to view the updated pdf file?

Probably like an image file, in which you attach a query string with the date after the file name. name.pdf?ts=2017042601

If it ain't broke don't fix it

The problem is that the emails have already been sent so won't be able to add a query string.

Have the users clear their cache.

There are two kinds of people in the world: those who can extrapolate from incomplete data. There are only 10 types of people in the world, those who understand binary and those who don't.

Maybe the web server is caching the pdf

If it ain't broke don't fix it
