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"/>
