如果在IIS6中你的web.config中是以下配置：
这是在IIS6中我们习惯的经典模式的配置
< system.web>
" " " " " enableVersionHeader = "true " />
" />
< pages validateRequest = "false " enableEventValidation = "false " >
< controls >
< add tagPrefix = "webdiyer " namespace = "Wuqi.Webdiyer " assembly = "AspNetPager " />
< add tagPrefix = "FCKeditorV2 " namespace = "FredCK.FCKeditorV2 " assembly =" FredCK.FCKeditorV2 "/>
</ controls >
</ pages >
<!--
设置 compilation debug="true" 将调试符号插入
已编译的页面中。但由于这会
影响性能，因此只在开发过程中将此值
设置为 true。
-->
< compilation debug = "true " targetFramework = "4.5 " >
< buildProviders >
< add extension = ".html " type = "System.Web.Compilation.PageBuildProvider " />
</ buildProviders >
</ compilation >
<!--
通过 <authentication> 节可以配置 ASP.NET 使用的
安全身份验证模式，
以标识传入的用户。
-->
< authentication mode = "Windows " />
<!--
如果在执行请求的过程中出现未处理的错误，
则通过 <customErrors> 节可以配置相应的处理步骤。具体说来，
开发人员通过该节可以配置
要显示的 html 错误页
以代替错误堆栈跟踪。
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
< httpHandlers >
< add verb = "* " path = "*.aspx " type = "URLRewriter.RewriterFactoryHandler, URLRewriter " />
< add verb = "* " path = "*.html " type = "URLRewriter.RewriterFactoryHandler, URLRewriter " />
< add verb = "* " path = "/* " type = "URLRewriter.RewriterFactoryHandler, URLRewriter " />
</ httpHandlers >
</ system.web>
那么在IIS7中的集成模式的配置
应该
< system.web>
.
.
.
</ system.web>
加上：
< system.webServer>
< handlers >
< add name = "* " path = "*.html " verb = "GET " type = "URLRewriter.RewriterFactoryHandler, URLRewriter " preCondition =" integratedMode "/>
</ handlers >s
< validation validateIntegratedModeConfiguration = "false " />
</ system.webServer>
就可以了，希望对您有帮助，有问题请直接回复，谢谢。
