Hide query string from URL asp.net c#

I have this following url:
http://www.example.com?user=Ana
and I want to get http://www.example.com?Ana
How can I get it?

You can route example.com/Ana to Home/Index with parameter (you can change controller and action to what is needed). Just add new route to your routing dictionary
routes.MapRoute(
"UserPage",
"{controller}/{action}/{user}",
new { controller = "Home", action = "Index", user = "" }
);
You can read more about routing here at ASP.NET
NOTE:
as Alexei Levenkov said it requires .Net MVC to route it that way.

MVC routing vs. partial class

I have a request controller that is getting out of hand, and I want to divide the actions on several controllers while maintaining a clean URL. I'm trying to experiment with routing, but without success. I've read some examples and tutorials on routing, but, though I understand the examples, nothing seems to apply to my case, and I feel non the wiser. What I want is for the URL Requests/Approval to be handled on my ApprovalController instead of my RequestController, so I wrote the following.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Approval",
"Request/{controller}/{action}",
new { controller = "Approval", action="Index", id = "" }
);
}
But it's not working. Why? I have a folder in the my Views called Approval, and in there I have a file called Index.cshtml. How should I code the MapRoute?
Edit
I added all the routes I've got

You need to swap the two MapRoute statements, like so:
routes.MapRoute(
"Approval",
"Request/Approval/{action}",
new { controller = "Approval", action="Index", id = "" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
The reason it is currently not working is because the first statement ('Default' route name) is getting matched before the second one is even evaluated.
In addition (as noted in my above example,) you need to remove '{controller}' in the Approval route and replace with 'Approval'... unless you specifically want the URL /Request/{ANY controller}/{action} to go through, which I doubt. From your question it seems you only want /Request/Approval/ to go to your Approval controller.
Don't forget to keep the Default route at the bottom, so as to match your other controllers and actions. It serves as a catch-all should no other matches exist.

The order you map your routes matters. Move the second route before the default route.
You will still have a problem though, as any thing /request/something will look for the SomethingContoller. To fix this, change your route to this:
routes.MapRoute(
"Approval",
"Request/Approval/{action}",
new { controller = "Approval", action="Index", id = "" }
);

MVC3 and Rewrites

I'm writing an MVC3 application that will need to make use of URL rewriting in the form of http://[server]/[City]-[State]/[some term]/ .
As I understand it, MVC3 contains a routing engine that uses {controler}/{action}/{id} which is defined in the Global.asax file:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
Traditionally (in a non-MVC app), I would use some URL rewriting flavor to decode a url such as http://www.myserver.com/City-State/somesearch/ to querystring parameters that look something like this:
http://www.myserver.com/city=City&state=State&query=somesearch
Keep in mind that this request would be coming from http://www.myserver.com/Home
Can this can be accomplished without having to specify a controller... something like this:
routes.MapRoute(
"Results",
"{city}-{state}/{searchTerm}",
new { controller = "Results", action = "Search" }
);
... or is it really best to have the controller listed?
How do you handle this in an MVC3 environment?
Thanks.

URL rewriting in asp.net MVC3:-
you can write code for url rewriting in Global.asax file :-
//Default url
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default",
"",
new { controller = "Home", action = "Index", id = "" }
);
//others url rewriting you want
RouteTable.Routes.MapRoute(null, "Search/{City_State}/{ID}", new { controller = "Home", action = "Search" });

Check out these two answers:
ASP.NET MVC Routes: How to define custom route
Defining custom URL routes in ASP.Net MVC
Summary:
Specify custom routes before the default one.
Define specific routes before general as they may match both.
Default values are optional.
Specify default Controller and Action in the default parameter object.

You can do this by registering route in Global.asax file, but order to register the Route is important you must be register first Old route then new one.
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// for Old url
routes.MapRoute(
"Results",
"{city}-{state}/{searchTerm}",
new { controller = "Results", action = "Search" }
);
// For Default Url
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);

MVC routing issue

Currently I'am working on an MVC project in which I try to get a kind of dynamic routing working. My idea would be that i left the original route in the global.asax.cs, so this one will take care of every controller I make. For example the Contact and Account controllers.
Above controllers will have url's like
/Contact/
/Account/Logoff/ etc.
The second route I want to add is the one that is a kind of default route when there are no controllers found. In that case I assume this will be a route to a page or pagedetails.
Url's for example will be :
/BBQ/
/BBQ/Accesoires/
I have three routes added in the global.asax.cs which I think are correct. (Also in the correct order). Below I have added the routes:
routes.MapRoute(
"DefaultRoute", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Page", action = "Index", id = UrlParameter.Optional });
routes.MapRoute(
"DefaultPageRoute",
"{category}",
new { controller = "Page", action = "Index", category = UrlParameter.Optional });
routes.MapRoute(
"SecondLevelPageRoute",
"{category}/{subCategory}",
new { controller = "Page", action = "PageDetails", category = UrlParameter.Optional, subCategory = UrlParameter.Optional });
with this setup the calls to the controllers work fine, but to the pages like /BBQ/ it gives below error:
Server Error in '/' Application.
The resource cannot be found.
If I comment the first route and go the the /BBQ/ url it works like a charm. What am I overseeing in this routetable?

You put the default route first, so it is trying to go to a route defined by {controller = "BBQ", Action = "Index" }
That route should be the very last route. However, you need more detail in your routes. Just having a category route will cause problems.
For example, if this route is first
routes.MapRoute(
"DefaultPageRoute",
"{category}",
new { controller = "Page", action = "Index", category = UrlParameter.Optional });
Then a call to the URL /Contact/ will assume that you want to go to Page/Index/Contact not /Contact/Index/{id}. I would use a more specific route that signifies that you are browsing a category like:
routes.MapRoute(
"DefaultPageRoute",
"Category/{category}",
new { controller = "Page", action = "Index", category = UrlParameter.Optional });
So you will need to use a url www.mysite.com/Category/BBQ to view what you want, but I don't think that's all bad.

How can I create a friendly URL in ASP.NET MVC?

How do I generate friendly URLs within the ASP.NET MVC Framework? For example, we've got a URL that looks like this:
http://site/catalogue/BrowseByStyleLevel/1
The 1 is Id of the study level (Higher in this case) to browse, but I'l like to reformat the URL in the same way StackOverflow does it.
For example, these two URLs will take you to the same place:
https://stackoverflow.com/questions/119323/nested-for-loops-in-different-languages
https://stackoverflow.com/questions/119323/
EDIT: The friendly part of the url is referred to as a slug.

There are two steps to solve this problem. First, create a new route or change the default route to accept an additional parameter:
routes.MapRoute( "Default", // Route name
"{controller}/{action}/{id}/{ignoreThisBit}",
new { controller = "Home",
action = "Index",
id = "",
ignoreThisBit = ""} // Parameter defaults )
Now you can type whatever you want to at the end of your URI and the application will ignore it.
When you render the links, you need to add the "friendly" text:
<%= Html.ActionLink("Link text", "ActionName", "ControllerName",
new { id = 1234, ignoreThisBit="friendly-text-here" });

This is how I have implemented the slug URL on my application.
Note: The default Maproute should not be changed and also the routes are processed in the order in which they're added to the route list.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home",
action = "Index",
id = UrlParameter.Optional
} // Parameter defaults
);
routes.MapRoute("Place", "{controller}/{action}/{id}/{slug}", new { controller = "Place", action = "Details", id = UrlParameter.Optional,slug="" });

you have a route on the global.asax
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = ""}
// Parameter defaults )
you can define your own route like :
controller is the cs class inside the the controllers folder.
you can define your id - with the name you choose.
the system will pass the value to your actionResult method.
