My scenario is: I have a website which is ASP.NET WebForm. Users can create their own page on my web site, their page url would be something like this: (MyWebsite.com/UserPage). but It is actually: (MyWebsite.com/UserPages.aspx?q=UserPage). It means when you enter the url (MyWebsite.com/UserPage) It rewrites the url and shows you (MyWebsite.com/UserPages.aspx?q=UserPage) (but the address bar is always like (MyWebsite.com/UserPage).
Here's my code in my "UrlRewriting" class:
void context_BeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
if (app.Request.Path.Contains("/") && !app.Request.Path.Contains(".") && app.Request.Path.IndexOf("/") == app.Request.Path.LastIndexOf("/"))
{
string userPageTitle = app.Request.Path.Substring(app.Request.Path.IndexOf("/") + 1);
if (!string.IsNullOrEmpty(userPageTitle ))
{
app.Context.RewritePath(string.Format("UserPages.aspx?q={0}", userPageTitle));
}
}
}
Now here's my problem: as I said my project is ASP.NET WebForm, (So, all of pages have .aspx extension) I wanted to remove the .aspx extension in my Urls, I've tried some codes in web.config which were working properly (In normal cases), but In my case, if you enter (MyWebsite.com/UserPage) It will be considering this "UserPage", as "UserPage.aspx". How can I handle this?
I usually do this with Routing which is available in ASP.NET Web Forms 4+.
You register your routes (URL patterns) in Global.asax, and specify which ASPX page will handle that URL.
This example would have UserPage.aspx handle all URLs that weren't otherwise handled by other ASPX pages.
void Application_Start(object sender, EventArgs e)
{
RouteTable.Routes.MapPageRoute("UserPageRoute", "{*url}", "~/UserPage.aspx");
}
Then in your UserPage.aspx you can determine the URL requested by looking at the Request.Url object, eg. Request.Url.PathAndQuery.
Note that you may need some extra web.config settings for this to work, eg (to manage extensionless URL requests)...
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />

I'm using ASP.NET WebPages (not MVC) to route urls in Application_Start in my Global.asax file.
System.Web.Routing.RouteTable
.Routes
.MapWebPageRoute("", "~/Pages/Home.cshtml")
.MapWebPageRoute("products", "~/Pages/Products.cshtml");
How do I obtain the physical url (second parameter given to MapWebPageRoute method) when a request is made?
protected void Application_BeginRequest(object sender, EventArgs e)
{
// I want to be able to retrieve the .cshtml page url in this context
}
I tried Request.Url.AbsoluteUri.ToString() but that only gives me the mapped url.
I'm running in the Cassini developer server inside Visual Studio 2012, and I need to redirect clients from the legacy .asp pages to .aspx pages.
Note: Ideally I would redirect clients from .asp to a friendly url, and then internally do a rewrite to .aspx
POST /ResetClock.asp
HTTP/1.1 307 Temporary Redirect
Location: //stackoverflow.us/ResetClock
And then internally:
POST /ResetClock
rewrites into /ResetClock.ashx (Yes, I changed it to .ashx; that's the virtue of url rewriting).
Like what Hanselman did
This is a lot like what Scott Hanselman did:
Request for /foo.html
gives the client a redirect to /foo
client request for /foo
is re-written into /foo.html
The attempted hack
I tried the hack solution; alter the .asp page to force a redirect to the .ashx (and live to fight with the url re-write syntax another day):
ResetClock.asp
<%
Response.Redirect("ResetClock.aspx")
Response.End
%>
Except that Cassini does not serve .asp pages at all:
This type of page is not served.
Description: The type of page you have requested is not served because it has been explicitly forbidden. The extension '.asp' may be incorrect. Please review the URL below and make sure that it is spelled correctly.
Requested URL: /WebSite/FetchTimes.asp
Which points to a related issue. The solution I end up using cannot require anything that isn't already available on the IIS7.5. And it cannot require anything that needs access to the IIS Admin tools; and must exist entirely within the web-site (e.g. the web.config).
The question
How do I re-write .asp into something more ASP.net-ish?
Edit: Changed GET to a POST to thwart nitpickers who wonder why the 307 Temporary Redirect and not 302 Found or 303 See Other.
The solution is to create an IHttpModule. HttpModules let you intercept every request, and react as you desire.
The first step is to create the plumbing of an IHttpModule:
class UrlRewriting : IHttpModule
{
public void Init(HttpApplication application)
{
application.BeginRequest += new EventHandler(this.Application_BeginRequest);
application.EndRequest += new EventHandler(this.Application_EndRequest);
}
public void Dispose()
{
//Nothing to do here
}
private void Application_BeginRequest(object sender, EventArgs e)
{
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
}
private void Application_EndRequest(object sender, EventArgs e)
{
}
}
And then register our HttpHandler in the web.config file:
web.config:
<configuration>
<system.web>
<httpModules>
<add name="UrlRewriting" type="UrlRewriting"/>
</httpModules>
</system.web>
</configuration>
Now we have a method (Application_BeginRequest) that will run every time a request is made.
Issue client redirect if they ask for ASP page
The first order of business is redirect the client to a "clean" form. For example, a request for /File.asp is redirected to /File:
private void Application_BeginRequest(object sender, EventArgs e)
{
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
//Redirct any requests to /File.asp into a /File
if (context.Request.Url.LocalPath == VirtualPathUtility.ToAbsolute("~/File.asp"))
{
//Be sure to issue a 307 Temporary Redirect in case the client issued a POST (i.e. a non-GET)
//If we issued 302 Found, a buggy client (e.g. Chrome, IE, Firefox) might convert the POST to a GET.
//If we issued 303 See Other, the client is required to convert a POST to a GET.
//If we issued 307 Temporary Redirect, the client is required to keep the POST method
context.Response.StatusCode = (int)HttpStatusCode.TemporaryRedirect;
context.Response.RedirectLocation = VirtualPathUtility.ToAbsolute("~/File");
context.Response.End();
}
}
And then the internal rewrite
Now that the client will be asking for /File, we have to re-write that internally to an .aspx, or in my case, an .ashx file:
private void Application_BeginRequest(object sender, EventArgs e)
{
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
//Redirct any requests to /ResetClock.asp into a /File
if (context.Request.Url.LocalPath == VirtualPathUtility.ToAbsolute("~/ResetClock.asp"))
{
//Be sure to issue a 307 Temporary Redirect in case the client issued a POST (i.e. a non-GET)
//If we issued 302 Found, the buggy client might convert the POST to a GET.
//If we issued 303 See Other, the client is required to convert a POST to a GET.
//If we issued 307 Temporary Redirect, the client is required to keep the POST method
context.Response.StatusCode = (int)HttpStatusCode.TemporaryRedirect;
context.Response.RedirectLocation = VirtualPathUtility.ToAbsolute("~/ResetClock");
context.Response.End();
}
//Rewrite clean url into actual handler
if (context.Request.Url.LocalPath == VirtualPathUtility.ToAbsolute("~/ResetClock"))
{
String path = "~/ResetClock.ashx"; //no need to map the path
context.Server.Execute(path, true);
//The other page has been executed
//Do not continue or we will hit the 404 of /ResetClock not being found
context.Response.End();
}
}
IIS contains some basic url redirection
Starting with some unknown version of IIS, they added a (now mocked) form of URL Rewriting. It doesn't issuing a client redirect, only an internal re-write. But at least it could be used to solve my problem (responding to an ASP page with ASP.net content):
web.config
<configuration>
<system.web>
<urlMappings>
<add url="~/ResetClock.asp" mappedUrl="~/ResetClock.ashx"/>
</urlMappings>
</system.web>
</configuration>
The client will still appear to have found a resource at /ResetClock.asp, but the guts of the response will have come from /ResetClock.ashx.

void RegisterRoutes(RouteCollection routes)
{
routes.MapPageRoute("cats", "categories/{ct1}/{ct2}", "~/mypage1.aspx", false, new RouteValueDictionary { {"catname",""}});
routes.MapPageRoute("lists", "lists/{li1}/{li2}", "~/mypage2.aspx", false, new RouteValueDictionary { {"liname",""}});
}
and I have registered routes
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
but the problem is the first route works perfectly but it says resource not found in second route
the annoying thing is it is finding the proper route because if I comment the second route then it will give compile time error of no matching routes. I tried to redirect to the route with different methods but none works..
this is working
<a href='<%# GetRouteUrl("cats",new {ct=Eval("Category_Id"),catname=Eval("Category_Name")}) %>'
but this doesnt
<a href='<%# GetRouteUrl("lists",new {lid= Eval("List_Id"),liname=Eval("List_Name_Url")}) %>'>
it doesnt work even from code behind..
I even changed the route and added 1 more parameter and changed accordingly, but still it didn't find it..I even removed the optional parameter setting from the lists route, but still not working.. check the link below
checkitouthere
Click on readmore button or link in jquerytab or on image
it is working on local..
how does it works on local but not on server...
even when i put connection string of server in my local computer then it doesnt work....
it works on local with local connection string..
There is issue with your "Read More" url, try allowing "." in the web.config:
See this is working:
http://www.superduper10.com/lists/1/top-ten-european-cities-to-visit
If you are using .NET 4.0, you can set this flag in the system.web section of your web.config and it will allow you to have dot in the end of url:
<httpRuntime relaxedUrlToFileSystemMapping="true" />
See this:
"The resource cannot be found." error when there is a "dot" at the end of the url
I am using UltiDev Web Server Pro and have all my aspx files are located in a sub folder 'WebForms'.
I want to be able to default all requests for pages to this folder such that they can just type:
http://myserver/somepage.aspx instead of
http://myserver/WebForms/somepage.aspx.
Is this possible?
EDIT:
Here is the VB.NET version of the solution below including a check for case sensitivity:
If Not HttpContext.Current.Request.Path.ToUpper.Contains("/WEBFORMS/") Then
Context.RewritePath("/WebForms" + HttpContext.Current.Request.Path, False)
End If
You can use the Global.asax and the Application_BeginRequest to RewritePath to the final destination and still have the link without the WebForm path.
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if(!HttpContext.Current.Request.Path.Contain("/WebForms/"))
RewritePath("/WebForms" + HttpContext.Current.Request.Path, false);
}
It is necessary to register as soon as this user directly login
protected void Button1_Click(object sender, EventArgs e)
{
Membership.CreateUser(FNBox.Text, PassBox.Text, EmailBox.Text);
FormsAuthentication.RedirectToLoginPage(FNBox.Text);
}
Error:
"Could not find the resource.
Description: HTTP 404. Perhaps the desired resource (or one of its dependencies of components) is removed, has a different name or is temporarily unavailable. Look at the following URL-address and make sure it is correct.
The requested URL: / OrderTest2/login.aspx "
protected void LoginButton_Click(object sender, EventArgs e)
{
Control lgnview = (Control)LoginView2.FindControl("LoginForm");
TextBox usrbox = (TextBox)lgnview.FindControl("UserName");
TextBox pasbox = (TextBox)lgnview.FindControl("Password");
string user = usrbox.Text;
string pass = pasbox.Text;
if(Membership.ValidateUser(user,pass))
{
FormsAuthentication.RedirectToLoginPage(user);
}
}
This is work normally
Your default redirect login page is wrong. As you can see, you are getting a 404 error which means that IIS cannot find your OrderTest2/login.aspx page. Verify your path.
You can set the defaultUrl path in your web.config as below to a valid page path, this will fix the problem.
<authentication mode="Forms">
<forms loginUrl="/OrderTest2/login.aspx" defaultUrl="myCustomLogin.aspx" cookieless="UseCookies" />
</authentication>
