不会搞了，解决不了，你可以帮忙直接修改看看吗？下面是源代码，可以的话，你修改一下再贴出来。 <?xml version="1.0"?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <configSections> <section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/> </configSections> <appSettings> <!--主数据库服务器 --> <add key="DataBaseServer" value="(local)"/> <!--主数据库名称 --> <add key="DataBaseName" value="wapp"/> <!--主数据库用户 --> <add key="DataBaseUid" value="sa"/> <!--主数据库密码 --> <add key="DataBasePwd" value="admin"/> <!--后台目录名 --> <add key="AdminPath" value="M"/> <!--界面识别变量 --> <add key="VE" value="ve"/> <!--身份识别变量 --> <add key="SID" value="u"/> </appSettings> <RewriterConfig> <Rules> <!-- Rules for Blog Content Displayer --> <RewriterRule> <LookFor>~/Reg-(\d+)\.aspx</LookFor> <SendTo>~/Reg.aspx?rd=$1</SendTo> </RewriterRule> <RewriterRule> <LookFor>~/Forum-(\d+)\.aspx</LookFor> <SendTo>~/bbs/forum.aspx?forumid=$1</SendTo> </RewriterRule> <RewriterRule> <LookFor>~/uinfo-(.*)\.aspx</LookFor> <SendTo>~/bbs/uinfo.aspx?uid=$1</SendTo> </RewriterRule> </Rules> </RewriterConfig> <system.web> <compilation debug="false"> </compilation> <authentication mode="Windows"/> <customErrors mode="Off"/> <!--<customErrors mode="On"> <error statusCode="403" redirect="default.aspx" /> <error statusCode="404" redirect="default.aspx" /> </customErrors>--> <httpRuntime maxRequestLength="102400" executionTimeout="1200"/> <pages validateRequest="false"/> <healthMonitoring heartbeatInterval="0" enabled="true"> <providers> <clear/> <add name="SqlWebEventProvider" type="BCW.Health.Providers.SqlWebEventProvider"/> </providers> <rules> <clear/> <add name="WebBaseError" eventName="WebBaseErrorEvent" provider="SqlWebEventProvider"/> </rules> <eventMappings> <clear/> <add name="WebBaseErrorEvent" type="System.Web.Management.WebBaseErrorEvent"/> </eventMappings> </healthMonitoring> <httpModules> <add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter"/> </httpModules> </system.web> </configuration>
