Bug#583510: libocamlnet-ocaml-dev: Cannot set custom order for POST headers and unusual headers order.

[Romain Beauxis <toots@rastageeks.org>]

Package: libocamlnet-ocaml-dev
Version: 2.2.9-8
Severity: wishlist


Hi,

ocamlnet seems to not put the content-length and content-type headers 
in last position when sending a HTTP POST request.

Although I do not think this is against the specs, it certainly confuses 
some webserver.

For instance, this code:
    let call = new Http_client.post_call in
    let pipeline = new Http_client.pipeline in
    let http_headers = call#request_header `Base in
    let body = call#request_body in
    call#set_request_uri uri ;
    body#set_value request ;
    call#set_request_body body ;
    http_headers#update_field
         "Content-length"
         (string_of_int (String.length request));
    http_headers#update_field "Content-type" "text/xml";
    call#set_request_header http_headers;
    pipeline#add call ;
    try
      pipeline#run () ;

Produces a request of the form:
POST /(...) HTTP/1.1
Content-length: 592
Content-type: text/xml
Date: Thu, 27 May 2010 22:08:53 GMT
User-agent: Netclient
Host: www.host.com

Which is refused by the server:
HTTP/1.1 400 Bad Request
Date: Thu, 27 May 2010 22:08:53 GMT
Server: Apache

Additionaly, one cannot set a custom order for the headers so this cannot
be worked around...
