Since the last weeks we see many 404's on our sites caused by Chrome adding /cache/[hex-string]/ to the current page URL.

The hex strings we have seen are:

  • e9c5ecc3f9d7fa1291240700c8da0728
  • 1d292296547f895c613a210468b705b7
  • 408cfdf76534ee8f14657ac884946ef2
  • 9b0771373b319ba4f132b9447c7060a4
  • b8cd4270356f296f1c5627aa88d43349

If you search for these strings you get matches from different sites, but they are most likely auto-generated (/search/cache/e9c5ecc3f9d7fa1291240700c8da0728/ for example).

Is this a known issue with Chrome (or an extension)?

Are you running through any firewall or similar? I have not see anything like that, so i wonder if its caused by your local network setup? – Digital Lightcraft May 23 '12 at 22:44
Website traffic comes via nginx and then to Apache (Python), but that did not change. The hex strings are also not commits from our git repo. Because we only see them from Chrome, and the Google index contains similar sites (growing number each day), I suspect this is related to a recent version of Chrome or an extension. – Jan Fabry May 24 '12 at 11:48
Same problem here! You can add d31fee2103d18244b731b1623650ec2e to the list of strings. I would like to add that it is a select group of users that trigger these errors but always in chrome. I have seen chrome 18 and 19 so it's not a specific version. Also, there are a lot of search results. Most of them will be auto-generated, but a lot of them show traffic reports and such, so there are probably a lot of other sites who get these requests. – Johan May 31 '12 at 12:36

I looks like a bug in a chrome extension:

It is marked as "won't fix" by chrome developers, as it depends on the extension owners.
