         - fails on www.msbooks.com because the HTTP request EOL is incorrect;
           must be \r\n, not \n. Fixed - Dan Kegel

         - fails on www.cvlug.org because it never times out
           (well, it seems like forever) Added timeouts - Dan Kegel

         - fails on hosts that require a Host: header line (i.e. multiple
           virtual hosts with same ip address), fixed Dan Kegel
