ASP Routing Be Used To Create "clean" URLs For .ashx Handlers?
Jul 29, 2010I have some REST services using plain old IHttpHandlers. I'd like to generate cleaner URLs, so that I don't have the .ashx in the path. Is there a way to use ASP.NET routing to create routes that map to ashx handlers? I've seen these types of routes previously:
// Route to an aspx page
RouteTable.Routes.MapPageRoute("route-name",
"some/path/{arg}",
"~/Pages/SomePage.aspx");
// Route for a WCF service
RouteTable.Routes.Add(new ServiceRoute("Services/SomeService",
new WebServiceHostFactory(),
typeof(SomeService)));
Trying to use RouteTable.Routes.MapPageRoute() generates an error (that the handler does not derive from Page). System.Web.Routing.RouteBase only seems to have 2 derived classes: ServiceRoute for services, and DynamicDataRoute for MVC. I'm not sure what MapPageRoute() does (Reflector doesn't show the method body, it just shows "Performance critical to inline this type of method across NGen image boundaries"). I see that RouteBase is not sealed, and has a relatively simple interface:
public abstract RouteData GetRouteData(HttpContextBase httpContext);
public abstract VirtualPathData GetVirtualPath(RequestContext requestContext,
RouteValueDictionary values);
So perhaps I can make my own HttpHandlerRoute. I'll give that a shot, but if anyone knows of an existing or built-in way of mapping routes to IHttpHandlers, that would be great.

View 1 RepliesC# - Why Do We Need Http Handlers
Jan 5, 2011I understand that the http handlers process request but this is just theory as I don't understand it. Many 3rd party controls require adding a http handler in web.config. And sometimes we are required to create our own class with ProcessRequest method that implements IHttpHandler interface but I am confused to understand where Http handler fits in and what their roles are?

View 1 RepliesWhich Access Modifier For Event Handlers
Apr 1, 2010I've been programming ASP.NET for a number of years and have got into the habit of using the public access modifier when writing event handlers for nested controls. e.g.
LinkButton ln = new LinkButton();
ln.Click += new EventHandler(LinkClick);
....
public void LinkClick(object sender, EventArgs e)
I think I started using public because I ran into errors when using other modifiers. Is this the correct one to use here? Does it depend whether you're writing a Page / UserControl / other?

View 1 RepliesC# - Programmatically Set HTTP Handlers In .NET Application?
Nov 4, 2010I need to dynamically instantiate a web application from a console application. By this definition, I mean that my console application contains a web application that is not bound to IIS/XSP.Currently, I create the web application into a temporary directory and copy some forged files into it. These are a special Global.asax that maps to my own implementation of HttpApplication to use in the web application (I need to do some initialization at app start), then I forge special .asmx files that map to my own skeleton classes and dynamic plugins
foreach (IPlugin plugin in _target.Plugins)
{
WsdlSkeletonDefinition[] defs = plugin.GetWsdlSkeletons();
My approach works, but I'm not so satisfied by it because I have to write lots of garbage into file system, even if I eventually delete it all.I know I can control HTTP handlers via Web.config, but I don't want to forge a Web.config for that. I would like to create a mapping such as I can remove the .asmx extension from web services' URLs and still get them.For example, one of the default scripts is "LogbusManagement.asmx", which must be hard-coded into client APIs and the .asmx prevents portability to other platforms such as PHP. I want to make "LogbusManagement.asmx" equivalent to "LogbusManagement" and any extension. For this, I might use an HttpHandlerFactory.
My straight question is,like asked here by somebody else: is there a way to programmatically, possibly from Global.asax, to set IHttpHandlers or IHttpHandlerFactories for web applications?

View 1 RepliesHttpHandlers / Modules :: Trying To Get A Handle On Http Handlers?
May 27, 2010I have created a dynamic signature for our members in Asp.net 2.0 with VB code behind that they can use as a signature in various message boards using an http handler.This is the first time I have evered used a http handler and I am probably missing a step on how to use it.The direct url to the signature is:
[URL]where the ID is a particular member. This works fine on most message boards and if you copy the link directly in a browser window, but not in other message boards.In order for this signature to work on all message boards, the url syntax would need to be as follows:[URL] or something similar where the URL does not have question marks, equal signs and the file name ends in .png .How can I go about doing this where the link will go to my http handler and overlay text, etc.

Web Forms :: Event Handlers Not Triggering Any Longer?
Sep 14, 2010I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.
