I am using POST method,bellow is my code. I dont know how to send xml but i tried it.by using HTTPClient example,i does some changes.

_LIT8(KMimeType, "text/xml; charset=utf-8");
void CClientAppUi::HandleCommandL(TInt aCommand)
{
case EClientPost:
// Issue HTTP post to engine; first cancel possible existing transaction
iEngine->CancelTransaction();
iAppView->ResetL();

_LIT8(KUrl8,"http://10.10.8.3:8082/Mvts/AuthenticationUser");

_LIT(KUsername,"sagar");
_LIT(KPassword,"sagar123");
_LIT(KXmlData,"<?xml version=1.0 encoding=UTF-8?>\n"
"<USERS>\n"
"<Username>&KUsername</Username>\n"
"<Password>&KPassword</Password>\n"
"</USERS>)");
TBuf<KDefaultBufferSize> postData(KXmlData);
TBuf8<KDefaultBufferSize> postData8;
postData8.Copy(postData);

// Start transaction
TRAPD(err, iEngine->IssueHTTPPostL(KUrl8, KMimeType, postData8));
// TODO: Error handling

}


///Http client
void CClientEngine::IssueHTTPPostL(const TDesC8& aUri,
const TDesC8& aContentType,
const TDesC8& aBody)
{

// Parse string to URI
TUriParser8 uri;
uri.Parse(aUri);

// Copy data to be posted into member variable; iPostData is used later in
// methods inherited from MHTTPDataSupplier.
delete iPostData;
iPostData = 0;
iPostData = aBody.AllocL();

// Create HTTP connection
TRAPD(err, SetupConnectionL());
// User didn't select an IAP
if (err == KErrNotReady) {
HBufC* resTxCancelled = StringLoader::LoadLC(R_HTTP_TX_CANCELLED);
iObserver.ClientEvent(*resTxCancelled);
CleanupStack::PopAndDestroy(resTxCancelled);
return;
}

// Get request method string for HTTP POST
RStringF method = iSession.StringPool().StringF(HTTP::EPOST,
RHTTPSession::GetTable());

// Open transaction with previous method and parsed uri. This class will
// receive transaction events in MHFRunL and MHFRunError.
iTransaction = iSession.OpenTransactionL(uri, *this, method);

// Set headers for request; user agent, accepted content type and body's
// content type.
RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();
SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent);
SetHeaderL(hdr, HTTP::EAccept, KAccept);
SetHeaderL(hdr, HTTP::EContentType, aContentType);

// Set this class as an data supplier. Inherited MHTTPDataSupplier methods
// are called when framework needs to send body data.
MHTTPDataSupplier* dataSupplier = this;
iTransaction.Request().SetBody(*dataSupplier);

// Submit the transaction. After this the framework will give transaction
// events via MHFRunL and MHFRunError.
iTransaction.SubmitL();

iRunning = ETrue;
HBufC* resConnecting = StringLoader::LoadLC(R_HTTP_CONNECTING);
iObserver.ClientEvent(*resConnecting);
CleanupStack::PopAndDestroy(resConnecting);
}

hi,
When u request for the server using post method did you get any response back in MHFRunL() funtion of THTTPEvent::EGotResponseBodyData case?
