通过webconfig设置iis上传大小限制

使用requestFiltering字节设置大小
使用httpRuntime executionTimeout设置时间

代码实例如下

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="4294967295" />
            </requestFiltering>
        </security>
    </system.webServer>
    <system.web>
        <httpRuntime executionTimeout="1800" />
    </system.web>
</configuration>
