isapi的urlmap问题

[angle1219]

我作了一个url map的测试dll，根据MS提供的代码稍微作了修改，url跳转是没有问题了，但是地址栏上的url也换了。怎么让它网页跳转但是url还是我输入的url?
source code:
DWORD CURL_reWriteFilter::OnUrlMap(CHttpFilterContext* pCtxt,
PHTTP_FILTER_URL_MAP pMapInfo)
{

CHAR szRedirect [256];
bool bflag = false;

if (strstr (pMapInfo->pszURL, "Index/"))
{
//CHAR szRedirect [256];
// replace www.microsoft.com with desired server
if(strstr(pMapInfo->pszURL,"2.html"))
{
sprintf(szRedirect, "Location: http://%s\r\n\r\n", "10.16.50.12:9000/index.asp?page=2");
bflag = true;
}
if(strstr(pMapInfo->pszURL,"3.html"))
{
sprintf(szRedirect, "Location: http://%s\r\n\r\n", "10.16.50.12:9000/index.asp?page=3");
bflag = true;
}
if(strstr(pMapInfo->pszURL,"4.html"))
{
sprintf(szRedirect, "Location: http://%s\r\n\r\n", "10.16.50.12:9000/index.asp?page=4");
bflag = true;
}
if(!bflag)
{
sprintf(szRedirect, "Location: http://%s\r\n\r\n", "10.16.50.12:9000/index.asp?page=1");
}
pCtxt->ServerSupportFunction ( SF_REQ_SEND_RESPONSE_HEADER,
(LPVOID) "302 Redirect",
(DWORD *) szRedirect,
0 );
// Print a message to the debug window
//ISAPITRACE1 ("Redirecting to: %s\n", szRedirect);
// we are done with this request
// return SF_STATUS_REQ_FINISHED_KEEP_CONN;
return SF_STATUS_REQ_HANDLED_NOTIFICATION;
}
// URL did not contain a DoRedirect string.
return SF_STATUS_REQ_NEXT_NOTIFICATION;
}

现在的效果是：我输入：http://localhost/Index/2.html，网页直接跳转到http://10.16.50.12:9000/index.asp?page=2,希望的效果是url上显示仍然是我输入的：“http://localhost/Index/2.html”，显示内容为：“http://10.16.50.12:9000/index.asp?page=2”，应该怎么实现？

这个问题很难吗？vc我不太懂，只想作一个url rewrite的测试功能，按说不是很困难吧
