Am seeking an answer as to why the following happens.
One of the guys working on our website uploaded a new version of a PDF (file name unchanged) to our website. In spite of repeatedly clearing his cache and using multiple browsers to access the site, he could not access the new version of the PDF that he had uploaded. Meanwhile the rest of us on the team all saw the new version the same day. Almost two weeks go by and our friend still keeps pulling up the old version in his browser. While on the phone with the guy, I log in to Cloudflare and purge that specific file from the cache. He then enters the url and walaaa he is pulling up the new version of the file.
My question is: why did I have to purge the Cloudflare cache in order for him to get access to the new file while the rest of us had near instantaneous access to it?
Any insights into this will be greatly appreciated.
