After some, but not all, 200 image requests in my Apache logs, I'm seeing a 408 error exactly 20 seconds later from the EO1's IP address. For example:

xx.xx.xx.xx - - [10/Feb/2019:16:48:12 -0500] "GET /vsmp-eo/frames/4756.png HTTP/1.1" 200 1081633
xx.xx.xx.xx - - [10/Feb/2019:16:48:32 -0500] "-" 408 -

This also seems to happen when the page is open in Chrome on my Mac, but not Safari. Googling suggests that Chrome is pre-connecting based on predicted browsing behavior to improve browsing speed, but this happens even if I:

• Disable Chrome's Use a prediction service to load pages more quickly setting
• Set the x-dns-prefetch-control meta tag in the HTML as in a990da7 (which has related links)
• Send the related header for images as well by setting Header set X-DNS-Prefetch-Control "off” in my Apache config

While I was initially concerned that images were not getting loaded properly, I no longer this is likely to the case, so it's probably not urgent to fix.
