Asp.net url重写后页面回发地址改变的处理

在Url重写的页面中进行PostBack并且不跳转的情况，会导致URL变回URL重写前的原始URL，这样的体验不太好，但是这种请况可以通过以下方法进行处理：

在微软的URLRewriter类库中添加以下类之后编译后，然后在项目中引用该UrlRewriter.dll文件

}

URLRewriter类库代码可以在UrlRewriter下载

然后在App_Browsers文件夹下创建Form.browser

代码如下：

<!--
可在 <windir>\Microsoft.NET\Framework\<ver>\CONFIG\Browsers 中找到现有的浏览器定义
-->
<browsers>
  <browser refID="Default">
    <controlAdapters>
      <adapter controlType="System.Web.UI.HtmlControls.HtmlForm"
               adapterType="URLRewriter.FormRewriterControlAdapter" />
    </controlAdapters>
  </browser>
  
    <browser id="NewBrowser" parentID="Mozilla">
        <identification>
            <userAgent match="Unique User Agent Regular Expression" />
        </identification>

        <capture>
            <userAgent match="NewBrowser (?'version'\d+\.\d+)" />
        </capture>

        <capabilities>
            <capability name="browser" value="My New Browser" />
            <capability name="version" value="${version}" />
        </capabilities>
    </browser>

    <browser refID="Mozilla">
        <capabilities>
            <capability name="xml" value="true" />
        </capabilities>
    </browser> 
</browsers>

在处理重写成html的时候本来网站中的html页面将会不能使用

使用以上方式将不存在这个个问题

如果还不行可以在<compilation debug="true">节点下添加

<buildProviders>
<add extension=".html" type="System.Web.Compilation.PageBuildProvider" />
</buildProviders>

在<httpHandlers>节点下添加（如果之前使用的是http处理程序执行重写的，请写在前面）

<add path="*.html" verb="*" type="System.Web.UI.PageHandlerFactory" validate="true"/>
