I guess that's a reasonable bug. Let's see what triage says.

on every request on pages that don't have a favicon
http://code.google.com/p/chromium/issues/detail?id=39402

I am seeing this bug myself, but I believe servers/scripts are handling
request improperly. View this example of a one-page request from Chrome and
Firefox.

Chrome requests the page, then the favicon. It then sends a HEAD request to
that page. My server was at default configurations, and was treating the
HEAD calls like GET or POST -- The script executed!

You can see that Firefox does not make this HEAD call below.

Scripts (or server configs) need to check for HEAD requests and deal with
them as needed. They are a standardized request.

http://code.google.com/p/chromium/issues/detail?id=39402

I am also facing the same problem and due to this my site crashes as we
have used URL rewrite using .htaccess and any invalid request to our site
removes session. Best solution is if <link> attribute is provided in HTML
then and then chrome should send request for facicon. It should not send
request on its own. It should be as per the configuration of site owner.

Yes, this really needs to be looked at. In the absence of HTTP/1.1 support
on the server this generates (and subsequently tears down) an extra TCP
connection for every page view. It's a source of gross inefficiency.

This bug actually causes a race issue here (I work for a web development
company) server-side leading to some form posts being rejected. There
probably is some better fix for us rather than ensuring we have favicons
but I think this issue should be fixed in Chrome too.

For those of you who are experiencing issues, it would help to have a
net-internals log.

See http://dev.chromium.org/for-testers/providing-network-details for
details.

There maybe multiple underlying causes for the same symptom.

#23: Thanks for the net-internals log. In this case the behavior is the
same as what I observed: a 404 is returned without any caching headers.

According to HTTP specs, 404 response codes should not use freshness
heuristics on 404 responses, so we are doing things correctly at the
caching layer. Basically, we can't use the cached negative response.

That being said, we may be able to do some hacks at the icon fetching layer
to use the stale 404 response in this case.

Also, it doesn't look like there is a Last-Modified header in this case, so
heuristic caching also wouldn't work under the normal approach. We should
see how other browsers handle this behavior, however.

Just tried with a site that had similar non-cacheable 404s in Firefox
16.01. In this case the favicon.ico was not refetched during the session.
New sessions would re-retrieve it. So, there is probably some icon-specific
caching that is going on separate from HTTP cache.

Yes, I think Chrome's behavior is correct in general, it's just this
particular case with favicon which needs special treatment. Trying this
with IE9 it does the same as Firefox and caches the 404.

I'm using Chrome Version 22 and it keeps on making 2 request to the server,
one a GET and then HEAD.

::1 - - [24/Oct/2012:23:38:24 +0300] "GET
/sapama/en/properties/myproperties/return_property_features_view HTTP/1.1"

How can I fix this? Do I have to test for HEAD request in my server?

request on pages that don't have a favicon

I think correct Chrome behavior would be to only request a favicon file if
referred in HTML:

<link rel='shortcut icon' type='image/x-icon' href='/favicon.ico' />

Also note that replicating this issue does not require Apache at all.
Simply put, anything answering port 80 gets these unsolicited favicon
requests, e.g. my teapot.

Another issue i have with this, is that the F12 inspector does not show
this hidden activity on the Network tab. Returning error 404 or 418 makes
no difference whatsoever.

it wouldn't add to extra parsing overhead to recognize the shortcut would

Another issue i have with this, is that each new favicon.ico request is a
new (why?) session. And because each session stays open at the server for
some extended period of time, this is a huge waste of resources. Each user
click, each request.

Note that this W3C QA page mentions that "Putting the favicon at a
predefined URI" is discouraged, and the HTML link tag is also suggested
here.
http://www.w3.org/2005/10/howto-favicon
I personally agree with the above.

Which is why i would like to learn whether the above issue resolution is a
temporary measure or considered a permanent fix, and -even more so- if the
latter i'd like to hear the motivation to load the fixed url, seemingly
regardless of HTML link tag.
I'd like to understand.

request on pages that don't have a favicon

Sorry for spamming this issue..
For reference, other browsers only load `/favicon.ico` optionally, and by
default thats disabled. (source
http://en.wikipedia.org/w/index.php?title=Favicon&oldid=554726736#How_to_use
)

^ Firefox only accepts favicon.ico in the web site's root without a <link>
tag if the setting browser.chrome.favicons is set to true in about:config.
The default value is true. If set to false, these favicons are ignored.
^ Opera loads /favicon.ico only if Multimedia/Always load favicon option in
opera:config is set to 1. See Opera Support page for more details.

I'd like to see Chrome behave like (pre-chromium) Opera here.

Chrome's behavior in regards to predefined "favicon.ico" vs <link
rel="icon"> is not the subject of this issue. Chrome DOES recognize <link
rel="icon"> and DOES NOT request predefined favicon.ico in such case.

This particular issue is about Chrome's relentless requests for favicon if
server doesn't have it.

Comment #57 on issue 39402 by ma...@mazurok.com: Chrome requests favicons

on every request on pages that don't have a favicon

https://code.google.com/p/chromium/issues/detail?id=39402

Server side: Node.js
Client side: Chrome 39.0.2171.95 m
Every time I try to load the page, server gets 3 requests. First with
url="/", and then two requests with url="/favicon.ico".

Same server, but on client side running clean portable build of Chromium
Version 39.0.2150.5 (7d466dc36d619ad23f32fabff9fc9bab25fbab58) (64-bit).
Server gets two requests per every page load. First with url="/", and then
two requests with url="/favicon.ico". Same issue with clean portable Chrome
Version 39.0.2171.95.

BUG IS NOT FIXED.
And must be reopened. Thanks.

I can't repro on M39 stable - see a single favicon request the first time I
navigate to a page, which gets a 404 response, and then no others until
restart. You are returning a 404 error, right?

Could you upload a net-internals log of this happening?

No, I don't, seems like my fault.. But FireFox and IE sends only ONE
request after trying to load favicon.
FF sending about three requests for favicon in first load.
IE trying to load favicon several times when I reload the page, and "give
up" after that.

First attachment is the simplest server on node.js.
You can see increasing number of requests here: http://54.69.95.79:8080/.
Second attachment is logs from portable Chrome Version 39.0.2171.95. Hope
it will help.

I only see one favicon request there, not the two you indicated. And the
server is returning a 200 response, which is rather weird, and violates the
HTTP spec.

That having been said, we probably shouldn't be re-requesting the favicon
in that case, either because of the mime type (If we check that for
favicons) or because we receive the entire response sucessfully and it's
not an icon. There's no real standard here to key behavior off of,
unfortunately.

I'm also encountering this same 100% reproducible issue using a simple
node.js web server.

Chrome version 41.0.2272.89 (64-bit)

kenmo...@gmail.com, it is because you shuold return 404 error if you have
no favicon. else chrome will try to get it again and again. but if you will
return 404 error - chrome will remember this.

Comment #63 on issue 39402 by rafal.cz...@gmail.com: Chrome requests

favicons on every request on pages that don't have a favicon
https://code.google.com/p/chromium/issues/detail?id=39402

My setup:

- web server (OpenBSD's HTTPd)
- serving single file: index.html which content is:

<html>
<body>
<h1>Test</h1>
</body>
</html>

I do *not* provide a link to the 'favicon.ico', nor do I *ever* intend to -
it is neither a requirement, nor is it in any working draft.

This is clearly a bug in Chrome, when accessing a page, it
automatically "assumes" the existence of 'favicon.ico' and tries to get it.

Please, only use the HTML code for any files - do *not* try to pre-load
anything that's not defined!

This is plain wrong and really annoying to see 404 in your server logs
generated automatically by a web browser! Stick to the W3C standards.

Please, *STOP*!

Thank you.

Version 44.0.2403.130 m
Windows 7

I find with Charles Proxy that every 3rd party domain, that is, app, pixel
tracker, analytics tag etc, also gets a request to /favicon.ico
