示例1: Service

{
std::string method = request.GetMethod();
if (method == METHOD_GET)
{
long long lastModified = GetLastModified(request);

{
// servlet doesn't support if-modified-since, no reason
// to go through further expensive logic
DoGet(request, response);
}
else

long long ifModifiedSince = request.GetDateHeader(HEADER_IFMODSINCE);
std::cout << "ifModifiedSince: " << ifModifiedSince << std::endl;

// If the servlet mod time is later, call doGet()
// Round down to the nearest second for a proper compare
