ASP.NET中实现二级或多级域名(修改UrlRewrite) 摘自:
http://www.cnblogs.com/jzywh/archive/2005/09/29/246650.html 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

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
.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.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.LookFor + "$";
// Create a regex (note that IgnoreCase& ...
