The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF

打开表单偶尔会出现这个提示，解决方法：

web.config增加配置：

 

<configuration> 
    <system.net> 
        <settings> 
            <httpWebRequest useUnsafeHeaderParsing="true" /> 
        </settings> 
    </system.net> 
</configuration>
