Stephane Bortzmeyer With help from: Richard Stevens, author of the book "Unix network programming" for his book and his many examples (a lot of the code comes from him by copy-and-paste). Pierre Beyssac, author of the "bing" tool for examples of code and beta-testing. Christian Grimm for the ICP code. Samuel Tardieu for the SMTP code. The Pasteur Institute because the work was done when working on the French national Web cache project, while being an employee of the Institute. $Id$
