If all case referer is fake as nothing in pages references can produce such request.

Looks like some strange interaction of Google bar and IE 8 browser that produces bogus requests.

From Wikipedia

The data URI scheme is a URI scheme (Uniform Resource Identifier scheme) that provides a way to include data in-line in web pages as if they were external resources. This technique allows normally separate elements such as images and style sheets to be fetched in a single HTTP request rather than multiple HTTP requests, which can be more efficient.

Data URIs tends to be simpler than other inclusion methods, such as MIME with cid or mid URIs. Data URIs are sometimes called Uniform Resource Locators, although they do not actually locate anything remote. The data URI scheme is defined in RFC 2397 of the Internet Engineering Task Force (IETF).

In browsers that fully support Data URIs for "navigation", Javascript generated content can be provided as file "download" to the user, simply by setting window.location.href to a Data URI. One example is the conversion of HTML tables to downloadable CSV using a Data URI like this: 'data:text/csv;charset=UTF-8,' + encodeURIComponent(csv), where "csv" has been generated by Javascript.

The IETF published the data URI specification in 1998[1] as Proposed Standard on the IETF Standards Track, and hasn't progressed it since. The HTML 4.01 specification refers to the data URI scheme,[2] and data URIs have now been implemented in most browsers.

I had a look into this a few weeks ago, and it appears to be IE8 related
and concerns the google.com search page with the live search results and
preview - although I never got to the bottom of exactly how the mechanism
is supposed to work and then fails. (somehow a mismatch between google
toolbar and MSIE8???)

I guessed at that time that google had invented some specific way of
getting webmasters to put some code into their pages so as to get
preferential "preview" treatment, e.g.:

<[defanged] html>
<head>

<title>rogers and browne url(res: C: Program Files Google Google Toolbar
Component GoogleToolbarDynamic_mui_en_E11712C84EA7E12B.dll
findy_buttons.png)</title>

<meta name="keywords" content="rogers and browne url(res: C: Program Files

Mystery GET with url(dataimage-png;base64,iVBOR (Servlets forum at JavaRanch)

Browsing thru some access logs I found that starting about Oct. 23, I am getting occasional GET requests that start like this:

view plaincopy to clipboardprint?

  1. GET /Dogs/url(data:image/png;base64,iVBOR...
where the base64 text is about 1600 characters long. My Tomcat server responds with a 404 error to this GET.

Now, I see that there is a data URI scheme where this kind of string gets used, but what the sam hill is it doing in a GET to my perfectly ordinary HTML site containing no Javascript?

I was wondering if this is some sort of attack since only a few IP addresses are the source and the GETs repeat at short intervals some times.

Anybody got any idea why these suddenly appeared.

Bill p>

I've seen similar 404 errors after a visitor arrives as the result of a normal Google search.
The wanted page and its associated images are downloaded normally.
Then comes
"GET /url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADgAAAAOCAYAAAB6pd..... 404
The very long base64 code starting iVBORw0... can be decoded to this rectangular image:


The icon to the right hand end is a Google icon, so the phenomena may have something to do with Google.

Best regards, Eric.
