IIS 配置詳解 請求長度限制調整

當上傳一個超過30M的文件時，服務器會重定向至404.13頁面，報錯以下：

HTTP Error 404.13 - Not Found

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

 

此請求的查詢字符串的長度超過配置的 maxQueryStringLength 值

 

 

 

1、全局配置 C:\Windows\System32\inetsrv\config目錄下的applicationhost.config  （iis配置文件）

　　1. 配置節system.webServer/security/requestFiltering/ 下增長如下配置

　　　　maxAllowedContentLength的單位爲Bytes

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

 

2、局部配置　

　　1.  applicationhost.config容許配置覆蓋， "Deny" to "Allow" like so: （IIS7.5 默認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/節下增長如下配置

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

　　Web,config

<configuration>
  <system.web>

　　　　<httpRuntime maxRequestLength="999999999" maxQueryStringLength="2097151" />

  </system.web>
</configuration>
