What does status=canceled for a resource mean in Chrome Developer Tools?

Question

What would cause a page to be canceled? I have a screenshot of the Chrome Developer Tools.

Answer 1

Chrome Version 33.0.1750.154 m consistently cancels image loads if I am using the Mobile Emulation pointed at my localhost; specifically with User Agent spoofing on (vs. just Screen settings).

When I turn User Agent spoofing off; image requests aren't canceled, I see the images.

I still don't understand why; in the former case, where the request is cancelled the Request Headers (CAUTION: Provisional headers are shown) have only

• Accept
• Cache-Control
• Pragma
• Referer
• User-Agent

In the latter case, all of those plus others like:

• Cookie
• Connection
• Host
• Accept-Encoding
• Accept-Language
