Stephane Bortzmeyer With help from: W. 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. Pierre-Yves Lochou for a lot of testing, debugging and porting. The Pasteur Institute because the work was done when working on the French national Web cache project, while being an employee of the Institute. $Id$
