I am trying to implement URL Routing for a non MVC application. Here's my original [URL] to [URL] I have difficulty when the page has query strings in the URL. This is the route handler I have so far:
public class CustomRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return BuildManager.CreateInstanceFromVirtualPath("ProcessStuff.aspx", typeof(Page)) as Page;
}
}
I started using url routing for my web application. It's a dynamic website and it has more than 50k pages. It looks like now it works slower. how to optimize it, to improve it and make it more efficient?
View 1 RepliesTo clarify, the scenarios I am looking at involve deploying ASP.NET 4 Web Forms application that employ RouteTable.Routes.MapPageRoute:
public class Global : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
RouteTable.Routes.MapPageRoute("questionnaires", "questionnaires", "~/Pages/Questionnaires/List.aspx", false);
[Code]....
Scenario 1: The application is NOT hosted as a virtual directory in an existing website, but is a stand-alone website (it is its own starting point). It has its own application pool. When deployed, it worked without any tinkering.
Scenario 2: The application is hosted as a virtual directory underneath an existing website. It also has its own application pool. However, I received 404 errors when trying to access the routes I had mapped out. Fortunately, I had experience getting MVC to work in 3.5 sp 1, so I tried that method: opened the properties dialog of the virtual director, went to the "Directory" tab, click the "Configuration" button, and added a Wildcard application map to the aspnet_isapi.dll and unchecked the "Verify that file exists" checkbox. This made it work.
My question is why did I have to add a wildcard application map in the second scenario but not the first? If it helps, the root website that hosts the virtual directory in the second scenario is set up with ASP.NET version 2.0.50727.
I've been developing a asp.net/c# web application that uses .net routing with Visual Studio 2008. The project is setup to use http://localhost:17315 as the server path. I'm trying to figure out a way for a co-worker to connect to my local project from their system. When I setup the project as a virtual directory in IIS (5.1) the .net routing doesn't work correctly and I get a 404 error (http://localhost/home).Is there anyway for a user on our local network to connect to my application remotely with my current configuration? I know they can't connect to the Visual Studio Development Server, but I would think they should be able to connect if the application is setup in IIS. Maybe IIS6+ is needed for this?

View 2 RepliesI have a new MVC app and a legacy ASP.NET app under a root website. They are isolated from one another in different application pools.Is it possible to leverage System.Web.Routing at the root website as an umbrella filter to seamlessly route (URL rewrite) requests to one app or the other to be transparent to the user?
View 3 RepliesI need to use routing with parameters in my ASP.NET application.
public class Global : System.Web.HttpApplication

void Application_Start(object sender, EventArgs e)
Then, by navigating to "/Profile" I want to get on Page_Load method Request.Params["Id"] as null and by navigating to "/Profile/1", Request.Params["Id"] as "1".
Thus far working with asp.net webforms was very easy .... But never implemented URL Routing in webforms... I know asp.net MVC Handles URL Routing pretty well... How to get started with URL Routing in an asp.net webform application? For EX: [URL] i want it to be like [URL] Any good article to start with URL Routing asp.net 3.5
View 1 RepliesIn an asp.net mvc application, I would like to be able to generate views, where the routing engine will create all URLs that point to a different site, i.e. change the application path.

ASP.NET 3.5 SP1 with Web Forms Routing thru Global.asax (System.Web.Routing and RegisterRoutes)IIS 7
Everything is working fine in my local machine, but it gives the following error in my hosting environment:
Could not load file or assembly 'System.Web.Routing, Version=3.5.0.0, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I did everything inside my web.config file mentioned in the following link:

But I am still getting the above error.
What else am I supposed to do fix the error?
I am using ASP.NET 4.0 Web Forms. I learned that, in order to optimize my Web Application for Search Engine, I must implement custom 404 page. But the way Microsoft tell us to implement custom 404 (within Web.Config file), that is not good for SEO. Microsoft says,
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="404" redirect="Page-Not-Found.aspx" />
</customErrors>
But when the page is not found, IIS issue 302 redirect to Page-Not-Found.aspx page which is not good. So, I implemented custom 404 page using Routing technique that is available in ASP.NET 3.5 SP1 and 4.0. I used the following router in Global.asax page
Imagine a Web Forms application with routing.
A clean page name like:
[URL]
Might have an underlying of URL of:
[URL]
If a user enters [URL] into a browser, I need to redirect to [URL]
Is this possible to do?
I can't work out a way to do this as the routing engine is not executed for a physical page and in the page.aspx Page_Load method I have no way of knowing whether the URL was entered directly or was the result of a route.
I am using linkbutton in my gridview to avoid the use of querystrings. The gridview is filled from a dataset.
I almost have it working but the text the linkbutton is displaying does not vary as a function of what row it is in. I need a way to associate the text of the linkbutton with the row it is in.

I have a Web application where i have added a reference to a RESTful WCF. I got the WCF url Routing to work in my webapplication by adding Inherits="RestService.Global" to the Web applications Global.asax.
<%@ Application Codebehind="Global.asax.cs" Inherits="RestService.Global" Language="C#" %>
But then i tried to create url Routing for the Web application and it does not work with the Inherits="RestService.Global" in the Global.asax. If i take it away it works fine. Is there a correct way to do this.
I'm trying to create my own CMS and I've gotten a little bit stuck at the stage of URL routing.
I want clean URLs without extensions and I'd like to be able to create and modify them in a web based interface without any messing around with IIS or actual files.
I've seen how to create a static route, but for that I need to go into my Global.asax file and manually add it.I would like to have all of these routes stored in a database so that I can easily modify them later.
Does anyone know how this can be achieved?
Just for extra information, I will be attempting to create a feature so that if a path exists, but is later changed, a 301 redirect is created to the new URL, is this also possible? (My first problem is the main issue, but thought I might ask this as well just in case it makes a difference)
I have a web application and I'm using asp.net routing. When I publish it with the Only files needed to run this application selected it gives me an error when I'm loading any of the page "HTTP Error 404 - File or directory not found."
but if I choose publish All files it works fine.
Do you know how to resolve this issue?
i have 2 dropdown list, menu and a gridview in my aspx page.

this querystrings should contain: the selected item in Menu, the dropdownlist1 selected value, dropdownlist2 selectev value and the gridview selected value.
how do i add all the controls value to my postbackurl ?

Is there a utility to combine querystrings? I'm looking for something like:
Input: Combine("test=a&test2=b", "test3=c") Result: "test=a&test2=b&test3=c"
Input: Combine("test=a&test2=b", "") Result: "test=a&test2=b"
Input: Combine("", "test3=c") Result: "test3=c"
And maybe some weird ones:
Input: Combine("&test=a&test2=b", "?test3=c") Result: "test=a&test2=b&test3=c"
I'm a novice ASP.Net/C# programmer, and had an experience only of a couple of projects during college and a couple of freelancing projects when I was recruited by a startup company to build their ASP.Net based website. I've just abut completed the website, and now since the company is not able to find a worthy enough SEO, I'm expected to do our site's SEO as well(which is a totally new experience for me). Did I mention that I'm the only Web Developer here?So, now as you'd expect a novice programmer having no concern for future SEO needs, I built up the site without giving due consideration to any of the SEO enhancement techniques.
The Problems:
ViewState - When is it required? Is it really required if I'm not creating any controls on the fly? I'm using DataControls though. And the website(the pages visible to the user not the CMS), is purely information based. Also, if I disable a control(ex: DataList)'s viewstate, will the viewstate of controls inside it also get disabled?(which is what I'd like actually)QueryStrings - Now comes the toughest part, I've used Query Strings to the extent that you can say that the website is QueryString driven, which unfortunately enough is not a good thing for SEO. To make matters worse, the QueryStrings for some pages are not uniform. For ex- In some cases the querystring may have variables A, B, and C, while in other cases it can have variables M, B, C and probably not all the three variables in some cases. Now, I know that I'd have to do url rewriting but these query strings have dynamic data fetched from the database tables of size more than 10,000 rows. So would I have to create functions for url rewriting and use regex to separate wheat from whaff?
I have been looking at ways of encrypting querystrings and I have found a few good examples.. but, I just want some clarification on what is most often referred to as the EncryptionKey and the characters that are in that key....Is there basically an unlimited number of alphanumeric combinations that could be used in the following code as the encryption key, is there anything that someone should be CAREFUL about including in that key?
using System.Security.Cryptography;
private static string EncryptionKey = "!#$a54?3";
/// other examples: "r0b1nr0y"
///in a try-catch:
key = System.Text.Encoding.UTF8.GetBytes(EncryptionKey.Substring(0, 8));
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
inputByteArray = Convert.FromBase64String(Input);
i have a querystring like this : Comparison.aspx?id=4545&Product=foo&displaylevelname=128
it's being build by 3 hidden fields in a html tablerow based on checkbox selection.
but user can select multiple checkboxes (20) and afterwards
i need a querystring like this : Comparison.aspx?id=4545&Product=foo&displaylevelname=128;145;455;
So how do i go from :
Comparison.aspx?id=4545&Product=foo&displaylevelname=128
Comparison.aspx?id=4545&Product=foo&displaylevelname=145
Comparison.aspx?id=4545&Product=foo&displaylevelname=455
To Comparison.aspx?id=4545&Product=foo&displaylevelname=128;145;455;
I have a page with some value like this:
[URL]
what I want to do is when the user enters values on the page I want to be able to change "valueA" and "valueB" in the URL without redirecting, refreshing or posingBack. Does anyone know how to do this?
I have a gridview which can be filtered from one or more values in a querystring. That all works great: e.g. "?subject=Maths&authorName=Bond_James&type=Magazine"
The values passed to the query string come from 3 drop down lists: Subject, Author, Type. What I'd like is when the user presses "Filter" it will take the selected values from the drop down lists and pass them to the querystring - it could be 1 value, 2, or all 3 (like above).
The drop down lists have an item called "All Subjects" / "All Author" / "All Type" each with a value of -1. The idea being that if the user leaves these items selected then the Filter button just ignores them.
Here is my code so far:
[Code]....
Also, one more thing. How do I get the drop down lists to have the filters selected when the page re loads?
EDIT: I changed the default values of the drop down lists to "" - this leaves the URL looking messy though ?author=&subject=&type= This works, is it the best way?
I'm having problems with accessing querystring params in my page method. Everywhere I read it says you can access querystrings just fine, but when I try it just returns null, what's the problem?
same problem I found - [URL]
I am wanting to develop a URL Rewriting solution that handles postbacks and querystrings. I have found a couple of examples, but don't fully udnerstand the code and don't want to implement code I don't understand. Obviously at the heart of this issue is intercepting the raw url before the rewrite occurs, however, I am not sure exactly how to go about this.
