- HTTP_HEADER.string does not have the ending CRLFCRLF .. but just CRLF - WGI_RESPONSE.write_header_text has the responsibility to handle the last blank line CRLF (separating the header from the message) - HTTP_HEADER.string does not set anymore a default content type as text/html - added WGI_RESPONSE.write_header_lines (ITERABLE [TUPLE [name,value: READABLE_STRING_8]] mainly as an helper method, this way the WGI user does not have to know about the CRLF end of line
