Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Host on Demand with a connection    *
  *                 to the host telnet server connection         *
  *                 through an HTTP proxy server.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: Host on-Demand client sessions are      *
  *                      unable to connect to a host telnet      *
  *                      server when the HOD client is           *
  *                      configured to use an HTTP proxy to      *
  *                      make the host connection.               *
  ****************************************************************
  * RECOMMENDATION: Users of Host on-Demand with a telnet        *
  *                 connection that connects through an          *
  *                 HTTP proxy server should consider            *
  *                 upgrading to the HOD code containing         *
  *                 this APAR.                                   *
  ****************************************************************
  The Host on-Demand client is unable to connect to the telnet
  server if the connection is configured to use a HTTP Proxy.
  The client session will display an error indicating it is
  unable to make a connection to the host system.
  
  The problem is occuring because the HOD client was sending an
  extra CRCF (carriage control line feed character) at the end
  of the header it sends to the HTTP Proxy. This extra character
  is a violation of the HTTP1.1 protocal.
  

Problem conclusion

• The Host on-Demand code was updated to correctly format the
  frames it was sending.
