IIS 配置详解 请求长度限制调整

当上传一个超过30M的文件时,服务器会重定向至404.13页面,报错如下:

HTTP Error 404.13 - Not Found

The request filtering module is configured to deny a request that exceeds the request content length.

 

此请求的查询字符串的长度超过配置的 maxQueryStringLength 值

 

 

 

一、全局配置 C:\Windows\System32\inetsrv\config目录下的applicationhost.config  (iis配置文件)

  1. 配置节system.webServer/security/requestFiltering/ 下增加以下配置

    maxAllowedContentLength的单位为Bytes

<system.webServer>
   <security>
       <requestFiltering>
              <requestLimits maxAllowedContentLength="40000000" />  
       </requestFiltering>
   <security>
<system.webServer>

 

二、局部配置 

  1.  applicationhost.config允许配置覆盖, "Deny" to "Allow" like so: (IIS7.5 默认Allow)

  

<sectionGroup name="security">
                <section name="access" overrideModeDefault="Deny" />
                <section name="applicationDependencies" overrideModeDefault="Deny" />
                <sectionGroup name="authentication">
                    <section name="anonymousAuthentication" overrideModeDefault="Deny" />
                    <section name="basicAuthentication" overrideModeDefault="Deny" />
                    <section name="clientCertificateMappingAuthentication" overrideModeDefault="Deny" />
                    <section name="digestAuthentication" overrideModeDefault="Deny" />
                    <section name="iisClientCertificateMappingAuthentication" overrideModeDefault="Deny" />
                    <section name="windowsAuthentication" overrideModeDefault="Deny" />
                </sectionGroup>
                <section name="authorization" overrideModeDefault="Allow" />
                <section name="ipSecurity" overrideModeDefault="Deny" />
                <section name="isapiCgiRestriction" allowDefinition="AppHostOnly" overrideModeDefault="Deny" />
                <section name="requestFiltering" overrideModeDefault="Allow" />
            </sectionGroup>

 

  2. Web。config文件 system.webServer/security/节下增加以下配置

 <requestFiltering>
        <requestLimits maxUrl="409600" maxQueryString="204800" maxAllowedContentLength="2097152" /> <!--单位字节Byte(2048000)-->
        <fileExtensions>
         
        </fileExtensions>
      </requestFiltering>

  Web,config

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="999999999" maxQueryStringLength="2097151" />
  </system.web>
</configuration>
