ASP.NET 网站开发日常异常总汇(持续更新)

1.問題點:使用FILEUPLOAD控件且上傳較大文件時,頁面顯示Internet Explorer 无法显示该网页

1.解決:在web.config中更改默認請求的最大字節數,如下,
    <httpRuntime maxRequestLength="102400" useFullyQualifiedRedirectUrl="true" executionTimeout="6000" minFreeThreads="8"  minLocalRequestFreeThreads="4"  
  appRequestQueueLimit="100" />

2.問題:JS與ASP.NET相互操作(刪除/增加COOKIES)
2.解決:JS document.cookie+="path=/",ASP.NET httpcookie.path="/"
    重要:保證JS與ASP.NET Cookie PATH相同

3.問題:使用AJAX.NET時,頁面顯示SYS未定義
3.解決:在WEB.CONFIG中,增加如下配置項:
    <httpHandlers>
      <remove verb="*" path="*.asmx"/>
      <add verb="*" path="*.asmx" validate="false" type="Microsoft.Web.Script.Services.ScriptHandlerFactory, Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
    </httpHandlers>
