New issue 132059 by benjamin...@gmail.com: Chrome causing 404's ending with
“/cache/[hex-string]/”
http://code.google.com/p/chromium/issues/detail?id=132059

Chrome Version : reproduced with 19.0.1084.52-2 19.0.1084.56 not with
18.xx
OS Version: Linux and Windows
URLs (if applicable) :

reproducible on this URL but can surely be reproduced elsewhere.
http://www.cinefil.com/cinema/multiplexe-mega-cgr-montpellier/


Other browsers tested:
Add OK or FAIL after other browsers where you have tested this issue:
Safari 5: OK
Firefox 4.x: OK
IE 7/8/9: OK

What steps will reproduce the problem?
1. point your browser to the URL and refresh a couple of time
2. Sniff the request sent by your browser via a proxy or look at the
website logs
3.

What is the expected result?

No request to /cache/[hex-number urls


What happens instead?

It seems that chromium issue incorrect requests to URL like:
http://www.cinefil.com/cinema/multiplexe-mega-cgr-montpellier/cache/[hex-number]


Please provide any additional information below. Attach a screenshot if
possible.

So far this behaviour has been noticed only on web site with a 'share
button' like share on facebook/twitter/addthis and so one.


Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.6 (KHTML, like Gecko)

the Hex number seems to be a pattern:

Also experiencing this issue from Windows NT users, only seen with version
19.0.1084.52 so far and site does not contain a "Share" button.

Sample request + user agent below:

As a website owner I don't see this from all Chrome browsers, so I suspect
it is caused by an extension. If you see this behavior from your browser,
could you please list the extensions you use?

I have tried to reproduce it by going to one of my websites (with this
problem) with multiple extensions installed.
I tried to look for extensions like cache or speed optimizers. No luck
however.

Hi,

We reproduced the problem on a chrome 19.0.1084.56 with no extra plugins.
But again it seems to happen only on certain website with some sort of
javascript.
We are a hosting company and I can see the problem on many website.

Have a go on this URL, go there throught a proxy and look at your proxy
logs.
http://www.cinefil.com/cinema/multiplexe-mega-cgr-montpellier/

You'll certainly see some requests to :

http://www.cinefil.com/cinema/multiplexe-mega-cgr-montpellier/cache/[hex-number]

Which should not happen.

I am 100% sure that this is on the browser side as many different web site
with complete different framework or CMS have those entry in the logs.



Thanks

My example of website uses protoculous.js (Prototype Version:"1.6.0.3"),
this is a homemade PHP website, not a CMS.

Hi,

Same issue on hand-made PHP site, we use a lot of JQuery. On some sites
with the issue, we don't have share buttons.

Hi,

This bug exists for quite long time.
First Chrome version i found in my logs is 12.0.742.91.

Also hex strings are commen between websites. For example:
9f6015e7e7ab284b2d697b3713c2f02f - now over 4000 hits in google...

Comment #19 on issue 132059 by zytza...@gmail.com: Chrome causing 404's
ending with “/cache/[hex-string]/”
http://code.google.com/p/chromium/issues/detail?id=132059

This smells of extension territory (mostly due to the way the cache/[hex]
urls appear to be generated + inability to repro on any of the
spotted "stock" Chrome versions).

Chrome versions / UAs spotted in the error logs range from 11 up to and
including 21. First errors spotted back around May 13. Increasing in
frequency since then. (on multiple, unrelated websites, regardless of
underlying architecture).

The general pattern is:

example.com/ -> example.com/cache/[hex]
example.com/something -> example.com/cache/[hex]
example.com/articles/article-title -> example.com/articles/cache/[hex]
example.com/reviews/view/190/ -> example.com/reviews/view/190/cache/[hex]

(last example is a different site exhibiting same behavior but with
trailing slashes in urls)

It's always an extra request "relative" to the originally requested URL
(but not truly relative). It seems the problematic requests are generated
by just appending "cache/[hex]" to the rightmost slash found within the
original url.

Hi,

I don't understand your comment "without a client side repro"
there are heaps of examples.

And the procedure to reproduce is rahter easy.
This is not related to a code injection and it is not a random request as
it is a pattern.

Chromium Browsers are currently spamming the internet with requests
looking like: [domainname]/cache/[hex]
I found those log entry on most of my server logs now.


Thank you for looking into this.

Thanks.

I see 20 requests, two of them have the pattern of this issue, and both
have LOAD_IGNORE_LIMITS as part of the flags (and they are the only two
requests with that flag).

I'm raising the priority until further investigation.

http://code.google.com/p/chromium/issues/detail?id=132059

Note the following code in resoruce_dispatcher_host_impl.cc

if (is_sync_load)
load_flags |= net::LOAD_IGNORE_LIMITS;

is *not* "sync" as in browser/sync, it is sync as in synchronous load.
Browser Sync doesn't have any special cased code / flags at this layer. Our
net loads all stem from http_bridge.cc (which is where we'd set flags).
Ricardo pointed out offline this may tie it back to a script running
somewhere (extension?).

Removing Feature-Sync for now.

That makes sense again :)

So this is a synchronous XHR. We don't issue those requests (synchronous
requests are nasty) so that brings us back to a script injected
somewhere... maybe an extension, maybe something else.

Are you using any extension? Do you mind disabling them (about:extensions)
and trying again?

having the same issue. even though i found a really good video on youtube
how to fix that (settings-->advanced settings --> uncheck "Predict network
actions to improve page load performance" and "Use a web service to help
resolve navigation errors" and restart the browser) it doesnt help since
all other major web users dont know about this and think the site is broken.

please fix asap!!

Matt, if #41 is correct that this is "caused by an extension," then I
believe we should remove Feature-Extensions and figure out an owner. Do you
see any reason for us to keep it?

Yeah, it sounds like this is caused by a particular misbehaving extension.

I think we are all seeing this issue in our server logs, not in our
browsers. For extension hint see comment #32.

The extension in question seems to be "Ginyas Browser Companion" (extension
ID bodddioamolcibagionmmobehnbhiakf). There's apparently a bug in their
code which makes it issue requests for http://.../cache/<md5>. This is not
an issue with Chrome, so I'm marking this WontFix.

I read this topic yesterday, while researching odd requests in our nginx
log.

Today however, I noticed more requests of this form, some of them
originating from my browser, which i verified does *not* have the
aformentioned extension installed.

However, I can't reproduce such requests, as the browser seems to be making
them randomly.

I suggest listing all extensions (with versions) before removing them. If
there isn't any, or anymore, please try to reproduce the bug, maybe the
browser should not be generating those requests by itself, but maybe it
does.
