微软的URLRewrite能够对URL进行重写，但是也只能对域名之后的部分进行重写，而不能对域名进行重写，如：可将 http://www.worldbao.com/showuser.aspx?us=suyiming  重写为 http://www.worldbao.com/suyiming.aspx  但不能将 http://www.worldbao.com/show.aspx?us=suyiming 重写为  http://suyiming.worldbao.com/

      要实现这个功能，首先要做域名泛解析，去域名管理里面的域名解析中添加一个：*.worldbao.com 指向服务器ip。

第二，重写URLRewrite里面的两个方法。

1.BaseModuleRewriter.cs  里面的BaseModuleRewriter_AuthorizeRequest方法

将

 

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication) sender;
            Rewrite(app.Request.Path, app);
        }

 

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication) sender;
            Rewrite(app.Request.Path, app);
        }

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)<br /> {<br /> HttpApplication app = (HttpApplication) sender;<br /> Rewrite(app.Request.Path, app);<br /> }

 

改为

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication) sender;
            Rewrite(app.Request.Url.AbsoluteUri, app);
        }

 

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication) sender;
            Rewrite(app.Request.Url.AbsoluteUri, app);
        }

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)<br /> {<br /> HttpApplication app = (HttpApplication) sender;<br /> Rewrite(app.Request.Url.AbsoluteUri, app);<br /> }

 

 

2， ModuleRewriter.cs  里面的 Rewrite 方法

将

 

    protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
    {
        // log information to the Trace object.
        app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");

        // get the configuration rules
        RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules;

        // iterate through each rule...
        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
            }
        }

        // Log information to the Trace object
        app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter");
    }
}

 

protected override void Rewrite(string requestedPath,
System.Web.HttpApplication app) { // log information to the Trace
object. app.Context.Trace.Write("ModuleRewriter", "Entering
ModuleRewriter"); // get the configuration rules RewriterRuleCollection
rules = RewriterConfiguration.GetConfig().Rules; // iterate through
each rule... 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 } } // Log information to the
Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting
ModuleRewriter"); } }

protected override void Rewrite(string requestedPath,<br /> System.Web.HttpApplication app) { // log information to the Trace<br /> object. app.Context.Trace.Write("ModuleRewriter", "Entering<br /> ModuleRewriter"); // get the configuration rules RewriterRuleCollection<br /> rules = RewriterConfiguration.GetConfig().Rules; // iterate through<br /> each rule... for(int i = 0; i < rules.Count; i++) { // get the<br /> pattern to look for, and Resolve the Url (convert ~ into the<br /> appropriate directory) string lookFor = "^" +<br /> RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath,<br /> rules[i].LookFor) + "$"; // Create a regex (note that IgnoreCase is<br /> set...) Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // See<br /> if a match is found if (re.IsMatch(requestedPath)) { // match found -<br /> do any replacement needed string sendToUrl =<br /> RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath,<br /> re.Replace(requestedPath, rules[i].SendTo)); // log rewriting<br /> information to the Trace object<br /> app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " +<br /> sendToUrl); // Rewrite the URL RewriterUtils.RewriteUrl(app.Context,<br /> sendToUrl); break; // exit the for loop } } // Log information to the<br /> Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting<br /> ModuleRewriter"); } }

 

改为

    protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
    {
        // log information to the Trace object.
        app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");

        // get the configuration rules
        RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules;

        // iterate through each rule...
        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
            }
        }

        // Log information to the Trace object
        app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter");
    }
}

 

protected override void Rewrite(string requestedPath,
System.Web.HttpApplication app) { // log information to the Trace
object. app.Context.Trace.Write("ModuleRewriter", "Entering
ModuleRewriter"); // get the configuration rules RewriterRuleCollection
rules = RewriterConfiguration.GetConfig().Rules; // iterate through
each rule... 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 } } // Log information to the
Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting
ModuleRewriter"); } }

protected override void Rewrite(string requestedPath,<br /> System.Web.HttpApplication app) { // log information to the Trace<br /> object. app.Context.Trace.Write("ModuleRewriter", "Entering<br /> ModuleRewriter"); // get the configuration rules RewriterRuleCollection<br /> rules = RewriterConfiguration.GetConfig().Rules; // iterate through<br /> each rule... for(int i = 0; i < rules.Count; i++) { // get the<br /> pattern to look for, and Resolve the Url (convert ~ into the<br /> appropriate directory) string lookFor = "^" + rules[i].LookFor + "$";<br /> // Create a regex (note that IgnoreCase is set...) Regex re = new<br /> Regex(lookFor, RegexOptions.IgnoreCase); // See if a match is found if<br /> (re.IsMatch(requestedPath)) { // match found - do any replacement<br /> needed string sendToUrl =<br /> RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath,<br /> re.Replace(requestedPath, rules[i].SendTo)); // log rewriting<br /> information to the Trace object<br /> app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " +<br /> sendToUrl); // Rewrite the URL RewriterUtils.RewriteUrl(app.Context,<br /> sendToUrl); break; // exit the for loop } } // Log information to the<br /> Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting<br /> ModuleRewriter"); } }

 

就是将

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

改成了

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

 

完成这过程之后将整个项目重新编译一下。

这些都做完之后，

在webconfig配置里面的
 <configSections>里面 添加：

<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>

 

<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>

<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>

 

在</configSections>下面添加

<RewriterConfig>
