Comment #6 on issue 276433 by
mme...@chromium.org: Double Redirect (HTTP
We've gone back and forth on sending cookies with favicon requests. IE has
its own separate cookie store for them, and we've seen sites with all sorts
of fun and interesting bugs related to favicon requests, some only
triggered when they do include cookies, some only triggered when they don't
include cookies.
While I know nothing about the favicon-specific code, we aren't getting a
404 for the favicon request for the above site. We're getting 2
uncacheable redirects followed by an uncacheable login page, so it clearly
can't be stored in the HTTP cache, at least.
