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

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 = "^" + 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
                }
            }

将

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

改成了

string lookFor = "^" + rules[i].LookFor + "$";


OK。
