Content-Type for POST request

Question

Hi all again,
I am setting content-type in the header to "text/xml"  yet when I do a POST sap sends as content-type
"application/x-www-form-urlencoded". Is there something else I need to set to make it post with text/xml ?
  cl_http_client=>create_by_url( EXPORTING url = url
                                           ssl_id = 'ANONYM'
                                 IMPORTING client = http_client ).
* create HTTP client object
*  cl_http_client=>create_by_destination( EXPORTING DESTINATION = 'ZTOLLREQUEST'
*                                 IMPORTING client = http_client ).
                                                                                * Set HTTP headers
  http_client->request->set_header_field( name = '~request_method'
  value = 'POST' ).
  http_client->request->set_header_field( name = 'Content-Type'
  value = 'text/xml' ).
*  http_client->request->set_header_field( name = 'Authorization'
*  value = auth_string ).
*  http_client->request->set_header_field( name = 'sap-password'
*  value = 'ymous' ).
                                                                                * Set payload
  http_client->request->set_cdata( xml_string ).
                                                                                * send and receive
  CALL METHOD http_client->send
    EXCEPTIONS
      http_communication_failure = 1
      http_invalid_state         = 2.

i havent tried this (setting content type) when using create by url . may be try just the create method and then set the remaining part of the url as headers ~request_uri parameter. something like below.
call method cl_http_client=>create
  exporting
    host          = 'www.webservicex.net'
    service       = '80'
    scheme        = '1'
    proxy_host    =  wf_proxy
    proxy_service =  wf_port
  importing
    client        = http_client.
http_client->propertytype_logon_popup = http_client->co_disabled.
wf_user = user .
wf_password = password .
call method http_client->authenticate
  exporting
    proxy_authentication = 'X'
    username             = wf_user
    password             = wf_password.
call method http_client->request->set_header_field
  exporting
    name  = '~request_method'
    value = 'POST'.
call method http_client->request->set_header_field
  exporting
    name  = '~server_protocol'
    value = 'HTTP/1.1'.
call method http_client->request->set_header_field
  exporting
    name  = '~request_uri'
    value = '/airport.asmx'.
