In my experience been using Canvas sincethis is just a temporary issue and reloading the page fixes it, and usually the cause is my school network, not the Canvas servers or my computer or browser.

There are various reasons why this may happen - your school or home network may be clogged or having other issues, Canvas servers are overloaded, your computer is overloaded, etc. When you load a page from a web server like Canvas, your web browser may actually be making dozens of requests from the server - one for each image and CSS and javascript file used on the web page.

This puts a brief but potentially heavy load on your computer, your home or school network, and the Canvas servers. For more discussion of this issue, see these threads on the Canvas community site: Disappearing Graphics and Why are my jpeg images disappearing.

Also, a little more work for the server - it has to get access to the file-last-modified time. Also, requires server-side information, so not suitable for a purely client-side-only solution to check for a refreshed image. When to use: When you want to cache images, but may need to update them at the server end from time to time without changing the filename itself. The idea here is that the cache-control header puts images in the browser cache, but immediately markes them stale, so that and every time they are re-displayed the browser must check with the server to see if they've changed.

This ensures that the browser's HTTP cache always returns the latest copy of the image. However, browsers will often re-use an in-memory copy of an image if they have one, and not even check their HTTP cache in that case. To prevent this, a fragment identifier is used: Comparison of in-memory image src 's includes the fragment identifier, but it gets stripped of before querying the HTTP cache. So, e. Works for servers that choke on a querystring added to a static image URL since servers never see fragment identifiers - they're for the browsers' own use only.
