Here is an extract of IIS Web Server :

[Tue Nov 06 07:50:49 EST 2001] ignoring request from loopback interface:
POST /spipe/pkg HTTP/1.0
Accept: application/octet-stream
Accept-Language: en-us
Content-Type: application/octet-stream
User-Agent: Mozilla/4.0 (compatible; SPIPE/2.0; Windows)
Host: 127.0.0.1
Content-Length: 447
Connection: Keep-Alive

What does it means, which application is doing what ?

SPIPE is part of ACE, the adaptive communications environment (http://www.cs.wustl.edu/~schmidt/ACE.html).

There's two potential explanations: Someone on the local server (using a program that uses ACE) accessed the server) or your IIS misinterpreted some IP-Address to be on the loopback.

The former is more likely.
