I keep getting calls to my server where there is random Javascript appended on the end of lots of the calls, e.g.:

/UI/Includes/JavaScript/).length)&&e.error(
/UI/Includes/JavaScript/,C,!1),a.addEventListener(
/UI/Includes/JavaScript/),l=b.createDocumentFragment(),m=b.documentElement,n=m.firstChild,o=b.createElement(
/UI/Includes/JavaScript/&&a.getAttributeNode(
/UI/Includes/JavaScript/&&a.firstChild.getAttribute(
/UI/Includes/JavaScript/).replace(bd,
/UI/Includes/JavaScript/)),a.getElementsByTagName(

The user agent is always this:

Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+2.0.50727)

I have jQuery, Modernizr and other JS and originally thought that some browser was messing up it's JS calls, however this particular IP address hasn't requested any images so I'm wondering if it is some kind of attack.

Is this a common occurence?
