Anyone know what could cause this pattern of http requests?

  • 772

It's from a registered user on my website.

Activity begins with normal looking URLs, which correlates to manual browsing, but then that stops.

After that I get the same GUID-based requests every 3 seconds for hours.

I suspect it's some sort of 'auto-refresh' tool, or maybe some tool to see if a page has changed, but since it's requesting an invalid URL that doesn't make much sense.

Note that the URL being requested actually includes the from HTTP/1.1 bit, which clearly isn't valid and so my server rightly returns a 404.

Any malfunctioning browser extension or software you know of with this pattern?
