I've been dealing with this since updating to IE10. I've tried adjusting the Internet Explorer settings to limit the size of this file but hadn't had any luck. In normal use this wouldn't be a problem, since in most cases, you have one user on a box and one webcache file, so a few gig isn't that big of a deal. But with WPM and 8 or so users all creating these files, it becomes a problem. My default NT verts only have 15GB available after the OS and app is installed. My only solution so far has been to create a powershell script that stops the player service at night, deletes the webcache files for each WPM user and then restarts the player process. I also have it clean up the WPM log directory at the same time. I'm spend most of my time in Unix and had no powershell experience, but would be happy to share what I have so far (and would certainly appreciate any suggested improvements)...
script so far...
