Recently I started to use Cloudflare to deal with requests for my company’s website. So far I am very impressed with the service and the ease of the transition, however I have come across one problem.
One part of the website is the ability for users to download files locally to their computer. This has stopped working since Cloudflare has been activated, what happens is the download gets initialised, and the wrong file size gets displayed. The browser proceeds to download (very low speeds - 100KB a second) until it reaches the originally advertised file size. Eventually when it reaches that file size it hangs for about 1 minute until the browser cancels the download and reports a ‘Failed - Network Error’ warning.
The files being downloaded are all PDF’s. It is worth noting that I don’t know how the files are server seeing as I did not build the website.
Is this a known issue with Cloudflare?
