ASP.NET 如何实现伪静态
其实所谓的伪静态页面,就是指的URL重写.

1.首先在web.config里写
<configSections>
    <section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>
</configSections>

2.在web.config里添加以下节点
<httpHandlers>
      <add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter"/>
      <add verb="*" path="*.html" type="URLRewriter.RewriterFactoryHandler, URLRewriter"/>
    </httpHandlers>

3.配置重写URL规则 (这里我们就以 *.html转到*.aspx为例子，当然也可以实现 http://www.a.com/a-1.html 转到 http://www.a.com/a.aspx?id=1   这种形式),

在configuration 加入一下节点
<RewriterConfig>
    <Rules>
      <RewriterRule>
        <LookFor>~/index.html</LookFor>
        <SendTo>~/index.aspx</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/Default.html</LookFor>
        <SendTo>~/Default.aspx</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/aboutus.html</LookFor>
        <SendTo>~/aboutus.aspx</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/aboutus_(\d+).html</LookFor>
        <SendTo>~/aboutus.aspx?ID=$1</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/Newslist.html</LookFor>
        <SendTo>~/Newslist.aspx</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/Newslist_(\d+).html</LookFor>
        <SendTo>~/Newslist.aspx?ID=$1</SendTo>
      </RewriterRule>
      <RewriterRule>
        <LookFor>~/Newsview_(\d+).html</LookFor>
        <SendTo>~/Newsview.aspx?id=$1</SendTo>
      </RewriterRule>
    </Rules>
</RewriterConfig>
