ASP.NET中实现二级或多级域名(修改UrlRewrite)
大家应该知道,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:// http://www.abc.com//1234/ 重写为 http://www.abc.com/show.aspx?id=1234 但不能将
http://1234.abc.com/ 重写为 http://www.abc.com/show.aspx?id=1234。
要 实现这个功能,前提条件就是 http://www.abc.com/ 是泛解析的,再就是要修改一下URLRewriter了。
总共要修改2个文件
1.BaseModuleRewriter.cs
改为
就是将 app.Request.Path 替换成了 app.Request.Url.AbsoluteUri
2.ModuleRewriter.cs
改为
将
string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";
改成了
string lookFor = "^" + rules[i].LookFor + "$";
完成这2处改动之后重新编译项目,将生成的dll复制到bin目录下。
再就是写web.config里的重写正则了
好了大功告成,你在IE地址栏输入 http://1234.abc.com/,就可以看到 http://www.abc.com/show.aspx?id=1234
的结果了
若你在实际应用中碰到了问题,请查看文章 "修改UrlRewrite以对域名进行重写"需要注意的问题 ,希望能够帮助你!

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

}

}

2.ModuleRewriter.cs
for

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
}
