I believe it is some protocol to bypass special caracters in URL for nastie robots to scan dynamic sites for e-mail adresses. It is mainly used by spammer robots.

But here is some important snip:
The ID "Microsoft URL Control - x.xx.xxxx" is part of the Microsoft MSINET.OCX that I believe is used by the WinInet API under Visual C++. Just because this one harvester is written with this library does not mean that all hits from this ID are coming from harvesters... other software developers MAY be using this API for more honest applications, like search engine robots.If you are a member of the Microsoft Site Builder Network, you probably do NOT want to block this ID. Site Builder's search robot was built with this OCX and thus identifies itself with this browser ID. If you block the agent, Site Builder will not be able to properly index your website.
