javascript - ubuntu Apache で Content-Type ヘッダーを許可する方法

Question

ApacheがインストールされたUbuntuサーバーボックスがあります。私は、オンラインの友達を追跡し、ユーザーがそれらとやり取りできるようにする単純な Web アプリを作成しています。アカウント管理全体のサーバープラットフォームとして、Commmunigate Pro を使用しています。ximss プロトコルを使用して Communigate に xml リクエストを送信しようとすると、Chrome コンソールに「リクエストヘッダーフィールドの Content-Type は Access-Control-Allow-Headers によって許可されていません」というメッセージが表示されます。リクエストにはjavascriptを使用しています。ximss 用の JavaScript クラスがあり、他のサーバーでも正しく動作することがわかっています。関連するコードは次のとおりです:
//index.php

var ximssSession = {
    serverName : "192.168.1.254:8100",
    theSession : null,

    doLogin : function (userName, passWord) {
        console.log("doLogin: "+userName + " " + passWord);
        var params = {
            userName        : userName,
            password        : passWord,
            serverName      : this.serverName,
            loginMethod     : "plain",
            asyncMode       : "syncPOST",
            binding         : "HTTP",
            pollPeriod      : 15
        };

        this.theSession = new XIMSSSession(params, this, this.ximssLoginCompleted);
    },

    ximssLoginCompleted : function (session, errorCode) {
        console.log("ximssLoginCompleted: "+errorCode);

        theSession = session;

        theSession.setAsyncProcessor(this, this.ximssAsyncAll,          null,           null, null);
        theSession.setAsyncProcessor(this, this.ximssAsyncSession,      "session",      null, null);
        //theSession.setAsyncProcessor(this, this.ximssAsyncPresence,   "presence",     null, null);
        theSession.setNetworkErrorProcessor(this, this.ximssNetworkErrorProcessor, 10);

        theSession.start();

        var presenceSetRequest = theSession.createXMLNode("presenceSet");
        presenceSetRequest.setAttribute("presence", "online");
        theSession.sendRequest(presenceSetRequest, this, null, null, false);

        var signalBindRequest = theSession.createXMLNode("signalBind");
        signalBindRequest.setAttribute("mode", "kill");
        theSession.sendRequest(signalBindRequest, this, null, this.ximssOpCompleted, true);
    },

    ximssAsyncAll : function (xmlData) {
        console.log("ximssAsyncAll: " + (new XMLSerializer()).serializeToString(xmlData));
    },

    ximssAsyncSession : function (xmlData) {
        console.log("ximssAsyncSession: " + (new XMLSerializer()).serializeToString(xmlData));
    },

    ximssAsyncPresence : function (xmlData) {
        console.log("ximssAsyncPresence: " + (new XMLSerializer()).serializeToString(xmlData));
    },

    ximssNetworkErrorProcessor : function (isFatal, timeElapsed) {
        console.log("network error");
    },

    ximssOpCompleted : function (errorCode, xmlData){
        console.log("ximssOpCompleted: "+errorCode);
        console.log("ximssOpCompleted: " + (new XMLSerializer()).serializeToString(xmlData));
    }
};

$(document).ready(function() {
    ximssSession.doLogin(
        <?php echo "\"" . $_SESSION["userName"] . "\"" ?>,
        <?php echo "\"" . $_SESSION["passWord"] . "\"" ?>
    );
});

//ximssclient.js

theSessionRef.startHTTPRequest = function(callback,method,url,body,userName,userPassword) {
  var httpRequest = new XMLHttpRequest();
  if(httpRequest == null) {callback(null,"XMLHttpRequest failed");}

  httpRequest.onreadystatechange = function() {

    if(httpRequest.readyState != 4) return;
    if(httpRequest.aborted) return;

    var errorCode = null;
    var ximssData = null;
    if(httpRequest.status == 0) {
      errorCode = "server communication error";
    } else if(httpRequest.status == 550) {
      errorCode = sessionLost;
    } else if(httpRequest.status < 200 || httpRequest.status >= 300) {
      if((errorCode = httpRequest.statusText) == null) errorCode = "server protocol error";
    } else if(httpRequest.responseXML != null) {
      ximssData = httpRequest.responseXML.childNodes[0];
      if(ximssData.tagName != "XIMSS") {ximssData = null; errorCode = "server XML response is not XIMSS";}
      else if(POSTXMLDocument == null) POSTXMLDocument = httpRequest.responseXML;
    } else {
      if(httpRequest.responseText != null && httpRequest.responseText != "") errorCode = "server response is not XML";
    }
    callback(ximssData,errorCode);
  }

  httpRequest.open(method,url,true,userName,userPassword);
  if(typeof(body) == "string") httpRequest.setRequestHeader("Content-Type","text/xml; charset=utf-8");
  httpRequest.send(body);
  return(httpRequest);
}

これは私のコンソールの始まりです：

"Header set Acces-Control_Allow_headers" という行を virtualhost ファイルに追加してみましたが、次のようになりました。

<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks

        </Directory>

                allow from all
                Header set Access-Control-Allow-Origin "*"
                Header set Access-Control-Allow-Headers "Content-Type"
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

その行を追加しても違いはありませんでした（もちろんApacheを再起動しました）。ここで何が欠けていますか？

これは私の要求です:

リクエストにリンクを url としてブラウザに入力するだけで成功します。これらの設定は GET とは異なりますか? また、IE でページを開くと、コンソールにエラーはなく、ximssOpCompleted メソッドの内容に到達します。
