我在我的asp.net应用程序中使用了使用自定义模块重写器的url重写，它正在工作，但问题是，当我单击任何按钮时，浏览器中的默认url都会更改为类似http://tipl.bizo.in/Download.aspx?busid=tipl应该由http://tipl.bizo.in/tipl/Download那么我该如何实现点击按钮
我的自定义模块重写器代码是：

{
// log information to the Trace object.
app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");
app.Context.Trace.Write("ModuleRewriter", "Requested Url: " + requestedPath);
string _stroriginalurl = app.Request.Url.AbsoluteUri.ToLower();
if (!string.IsNullOrEmpty(_stroriginalurl))
{

{
string _getparam = regurltest.Match(_stroriginalurl).Groups[3].Value;

{

}
}
}
}

}
}

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

string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";
// Create a regex (note that IgnoreCase is set...)

实际上urlrewrite只重命名了请求的url，但asp.net实际上对这个更改一无所知。因此，您必须更改代码中的某些内容，以使页面了解更改。这将是一个解决方案：
protected void Page_Load(object sender, EventArgs e)
{
form1.Action = Request.RawUrl;
}
