对于URL重写，支持无后缀url请求

有些资料讲如果要支持目录必须使用iiswriter,或者其他软件，其实通过简单对iis配置，再利用urlwriter就可以完美解决url重写的问题

可以将http://abc.domain.com/blog

转向到http://www.domain.com/xxx.aspx?username=abc

当然首先要将主机的泛域名支持打开。

做法是

A。打开IIS，右击站点（虚拟目录）－》属性－》主目录－》配置－》插入－》C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll，不确认文件存在－》确定

B。修改webconfig：

<RewriterConfig>
    <Rules>
      <RewriterRule>
        <LookFor>http://localhost/(blog)</LookFor>
        <SendTo>~/sdfsdf.asxp?tag=$1</SendTo>
      </RewriterRule>
   </Rules>
</RewriterConfig>

C。修改UrlRewriter
从微软下载源码，

1.BaseModuleRewriter.cs

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)

{

HttpApplication app = (HttpApplication) sender;

Rewrite(app.Request.Path, app);

}

改为

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)

{

HttpApplication app = (HttpApplication) sender;

Rewrite(app.Request.Url.AbsoluteUri, app);

}

就是将 app.Request.Path 替换成了 app.Request.Url.AbsoluteUri

2.ModuleRewriter.cs

for(int i = 0; i < rules.Count; i++)

{

// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)

string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";

// Create a regex (note that IgnoreCase is set

)

Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);

// See if a match is found

if (re.IsMatch(requestedPath))

{

// match found - do any replacement needed

string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));

// log rewriting information to the Trace object

app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);

// Rewrite the URL

RewriterUtils.RewriteUrl(app.Context, sendToUrl);

break; // exit the for loop

}

改为
