单个浏览器页面的几个未使用的会话

Question

测试 wt :: Wapplication 时，我的行为很奇怪。似乎一个浏览器窗口最多将触发3个会话。只有第一个会话将保留，因为其他2会将在不久之后到期。

有人会遇到类似的问题吗？

wt版本： 4.5.0 Windows Build

Main ：

int main(int argc, char **argv)
{
    return Wt::WRun(argc, argv, [](const Wt::WEnvironment& env) {
        return std::make_unique<Wt::WApplication>(env);
    });
}

该应用程序被调用：

--approot ../../../approot --docroot "../../../docroot;/styles.css,/images,/sitemaps,/robots.txt" --http-address localhost --http-port 8080

wt log：

后来重复最后一个。

我真的很乐意得到一些建议:) 此致

我假设为 http：//127.0.0.1：8080/resources/... 请求创建了两个额外的会话。将/Resources 添加到 docRoot 静态文件路径列表应防止此类请求启动新会话。

添加 -resources-dir/path/to/wt/install/install/share/wt/resources ，允许wt找到WT本身提供的资源，这也可能很有用。

资源：

• wt：library oferview
