url rewrite help

Try looking here:
http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module

could you help me giving me one final solution to my problem, This link you show me is not working. can you provide me the syntax to add on web.config.

You should have a web.config like the one below:

<rewrite>
  <rules>
    <rule name="Rewrite to Default.aspx">
      <match url="^photos/([0-9]+)/([0-9]+)/([0-9]+)" />
      <action type="Rewrite" url="app_g/Default.aspx?id={R:1}&amp;S={R:2}&amp;M={R:3}" />
    </rule>
  </rules>
</rewrite>

Select allOpen in new window

i got this error:
Server Error

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

What does the event log say?

I'm assuming you have IIS7 with ASP.NET role service enabled?  URL Rewrite Mod installed?

Hi Edward, The page is like that:
http://localhost/app_g/Default.aspx?id=173&S=1&M=12
I want to be like this.
http://localhost/photos/173/1/12

Question, is your code doing the opposite

Hi, i found this on the internet that say i need to change the global.asax file like this, but it does not give errrors and does not change the path.

<%@ Import Namespace="System.Web.Routing" %>
<script runat="server">
    Sub RegisterRoutes(ByVal routes As RouteCollection)
        routes.MapPageRoute("test", "color/{id}/{*queryvalues}", "~/app_g/Details.aspx")
    End Sub
   
    Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
        ' Code that runs on application startup
        RegisterRoutes(RouteTable.Routes)
    End Sub

ok, now i am starting to understand this. If i access the link:        
http://localhost:4565/app_g/Details.aspx?id=2 it will not change to the other page i route, but it will stay at this addres. But if I access this addres: http://localhost:4565/color/2/ it will work as the same. But what about if I access the first link with the ?id=2, is there anyway to change to the friendly path.

RouteTable.Routes.MapPageRoute("test", "color/{id}/{*queryvalues}", "~/app_g/Details.aspx")
