I 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 RepliesI am trying to get a captcha web control to display, but it isn't going into the HttpHandler that I created. This isn't my project and it is quite big so I'm not sure what is going on. Is there any tools or techniques to see which handler is being called.
View 4 RepliesI 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?
It is good experience by reading posts/discussions so im asp.net programmer i need the knowledge of how to work with http handlers? Where can we use them and what are exact scenarios in our requirement?
View 1 RepliesI 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.
am new to http handler concept and havent worked on it.What is http handlers and what is use of it??
View 1 Repliesi have a couple of xml files in my asp.net web application that i don't want anyone to access other than my server side code. this is what i tried..
<add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler" />
i wrote this inside the <httpHandlers>
it works well on the localhost but not in the server... the server without any hesitation displays the xml file... i have no idea how to proceed...

When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.

Background:
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
Response.OutputStream = WebRequest.Create(FacebookUrlForThumbnail)
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?

View 19 RepliesI have a bit confusion about the Http Handlers,Generic Handlers and the usage of those two.
View 1 RepliesI'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?
