How to deal with extensionless Url in ASP.Net and

问题:

I need a way to write the extensionless urls. My server is a Shared Host with IIS6.0 version 1. Currenty I am using UrlRewriting.Net dll,which supports only on IIS7.

My original url is abc.xyz.in/Index.aspx?c=comp_Name; My virtual url is abc.xyz.in/comp_Name.aspx but i want it as abc.xyz.in/comp_Name

Is it possible via any other module or anything. Please note mine host is shared host. So I cant either configure IIS on my own or force my admin to make modifications for the same.

The problem with custom routing in IIS6 (and older versions) is that they by default doesn't invoke the ASP.Net module unless you are asking for a .aspx, .ashx, .asmx file. There are some solutions to this that use a custom error that checks what you were trying to visit and then shows the correct page but it isn't a very nice solution (but if you really want to read more about it there is a sample over at CodeProject: http://www.codeproject.com/Articles/44475/IIS-vs-ASP-NET-URL-Rewriting).

My suggestion would be to ask your webhost to add a wildcard mapping for ASP.Net so that it handles all incoming requests to your site so you can write a proper routing module, they might not have to but there is no harm in asking and it can easily be set up on a site basis. If that is out of the question then you should probably look for a new webhost that can accommodate the needs for your site instead of adapting your site to your current webhost.

Hi you need to write your own HttpModule. This is a good example (it is from here): Have a look on that site, it will describe all steps needed.

using System;
using System.Web;


public class DavModule : IHttpModule {

    private HttpApplication context = null;

    public void Dispose() {
        context.BeginRequest -= new EventHandler(context_BeginRequest);
    }

    public void Init(HttpApplication context) {
        this.context = context;
        this.context.BeginRequest += new EventHandler(context_BeginRequest);
    }

    void context_BeginRequest(object sender, EventArgs e) {
        HttpApplication app = (HttpApplication) sender;
        app.Response.ContentType = "text/plain";

        if (app.Request.Path.EndsWith("Help"))
            app.Server.Transfer("Help.aspx");
        else {
            app.Response.Write("Path: " + app.Request.Path);
            app.Response.End();
        }
    }
}

If you are starting out (or if doing so is an option), the question becomes whether or not you (your host) have ASP.Net 4 on IIS (6 or 7).

Extensionless urls are part of ASP.Net 4 - which means your ASP.Net site/s (that you want to have extensionless urls working) have to be running on ASP.net 4 (not v2.x)...

Hth...
