What are the DISK_CACHE_ENTRY urls in chrome://net-internals/#events, and why are they happening when no remote resources are being asked for?
A google search mostly shows bug reports and source code — is there documentation on this event type available anywhere?
More info:
I am running Chromium Version 43.0.2357.81 Ubuntu 15.04 (64-bit).
The DISK_CACHE_ENTRY urls seem to be coming from my history. For example, I have no remote resources open, but I see this event appear (probably from a past Google Maps visit):
6409 DISK_CACHE_ENTRY http://maps.gstatic.com/maps-api-v3/api/js/21/4/common.js
To rule out that they are one of the requests in user-configurable Chrome operations, I disabled all extensions, uchecked all options under "Privacy", and disabled all account sync options. I opened only two tabs:
- chrome://net-internals/#events
- http://localhost/ (a simple directory listing with no remote urls)
The events still happen whenever I refresh the localhost tab.
