     这两天写程序中，遇到了RHTTPSession与RHttpDownloadMgr共享网络连接RConnection的问题，折腾了好久，最后终于解决。

 大体上的流程是先在appui中建立connection，然后分别设置RHTTPSession与RHttpDownloadMgr

我的方法是：

在APPUI中定义：

 RConnection iConnect;
 RSocketServ iSocketServ;

然后再初始化时：
InitConnectL()

{

        User::LeaveIfError(iSocketServ.Connect());
        User::LeaveIfError(iConnect.Open(iSocketServ));
        User::LeaveIfError(iConnect.Start());
     

         
        iClient->SetConnection(&(iConnect), &(iSocketServ));
        iDLMgr->SetConnection(&iConnect);
        iDLMgr->AfterConnectL();

}

   iClient->SetConnection(&(iConnect), &(iSocketServ));中的代码是：

 void CWebClientEngine::SetConnection(RConnection* aConnection, RSocketServ* aSocket)<br /> {<br /> LOG(_L("CWebClientEngine::SetConnection"));<br /> iConnection = aConnection;<br /> iSocketServ = aSocket;<br /> iConnectionSetupDone = ETrue; </p> <p> //set the sessions connection info<br /> RStringPool strPool = iSession.StringPool();<br /> RHTTPConnectionInfo connInfo = iSession.ConnectionInfo();</p> <p> //to use our socket server and connection<br /> connInfo.SetPropertyL ( strPool.StringF(HTTP::EHttpSocketServ,<br /> RHTTPSession::GetTable() ), THTTPHdrVal (iSocketServ->Handle()) );</p> <p> connInfo.SetPropertyL ( strPool.StringF(HTTP::EHttpSocketConnection,<br /> RHTTPSession::GetTable() ),<br /> THTTPHdrVal (REINTERPRET_CAST(TInt, (iConnection))) );<br /> }

        iDLMgr->SetConnection(&iConnect);
        iDLMgr->AfterConnectL();

中的代码是：

void SetConnection(RConnection* aConnection){ iConnect = aConnection; }</p> <p>void CDownloadMgr::AfterConnectL()<br /> {<br /> LOG(_L("CDownloadMgr::AfterConnectL")); </p> <p> TUint connCount = 0;<br /> // Count active connections<br /> iConnect->EnumerateConnections(connCount);</p> <p> if (connCount)<br /> {<br /> for(TUint i = 1; i <= connCount; i++)<br /> {<br /> TPckgBuf<TConnectionInfo> connInfo;<br /> // Get connection info<br /> User::LeaveIfError(iConnect->GetConnectionInfo(i, connInfo));<br /> //return connInfo().iIapId;<br /> User::LeaveIfError( iDMgr.SetIntAttribute( EDlMgrIap, (TInt32)connInfo().iIapId ) );<br /> break;<br /> //connInfo().iNetId;<br /> }<br /> }</p> <p>}
