Calling req.send_http_header() is only needed for mod_python 2.7.X and older. Even then, it should go after setting req.content_type. If still using mod_python 2.7.X, then upgrade. If you can't because you are using Apache 1.3, then consider using mod_wsgi instead and write your web application to WSGI API, using one of the many toolkits/frameworks out there for WSGI.
