Digging deeper into HttpHandlers I found they provide nice way to customize an ASP.NET application. I am new to ASP.NET and I want to know about different customizations that are possible using HttpHandlers. Lots of websites talk about how they are implemented but it would be nice to know some use cases beyond what ASP.NET already provides using HttpHandlers.
View 2 RepliesStarting to get frustrated with MVC and how everything is so helper based with one massive Html helper that just has everything in it. No more controls to inherit from, no events, nothing. I don't see what's the proper way to "customize" something. It's seems it take it or leave it or copy source code and start over again with yet more helper functions. And man, so much stuff in core mvc is internal or private so you end up copying a lot of code but then it won't work. I also don't see any events so that when the core helpers are generating an input element that I can hook in and customize there.
I'm trying to build a forms engine and I like all this new MVC 3 with data annotations, validation, etc. HOWEVER, for all my input controls I need to
1) Add javascript events for onkeydown, onchange, etc
2) Show validation errors using tooltips (was going to use a jqueryui plugin). Based on this, I really just want to place a Html.TextBoxFor and have it generate all the required validation stuff including it's own hidden ! to display should a validation error being present.
I'm using LLBL business objects so it's not so easy to go add attributes like [required] and stuff. Ideally, I'd like to layout the forms once, but then OUTSIDE the form, inside the helpers, or whatever method I use, there I can customize exactly how the input elements and validations are rendered. What is the easiest way to customize, hook, subclass, whatever, the current helpers so that I can generate input elements but with my own project's specific twists?
I have this code in Global.asax but it not firing once an error occured:

When exactly to use HttpHandlers and HttpModules?Can't I write that code in ASPX pages' code behind?
View 1 RepliesI need to get an image from a SQL Server as a byte[], and load it to a WebControl.Image. The only seemingly good way to do it that I found is to implement IHttpHandler and handle the request accordingly.But I'm stuck to using asp.net 1.1. Does it support ashx files?
View 1 RepliesI've defined a custom HttpHandler,
public class RequestHandler : IHttpHandler
Which I pass all my requests through,
<configuration>
<system.webServer>
<handlers>
<add name="RequestHandler" path="*" verb="*" type="WebApplication6.RequestHandler" />
</handlers>
</system.webServer>
Does this class get re-constructed every time someone requests a page or not?
How do we findout the whether the application is using any HTTPModules and httphandler in the applicaion?Is there anyway to findout from the url without checking the web.config file?
View 1 RepliesI've never fully understood this property of the IHttpHandler. It is a property that you have to set when you implement the interface. I've assumed that setting it to true would be better for performance, but I am not sure what the negative side effects might be. Should I return true or false?
View 3 RepliesI got a website [URL] and I want to redirect http://www.example.com/folder to http://folder.example.com so if

View 7 RepliesI have a HttpModule that rewrites the url:
eg: Folder/StaticPage.aspx?PageName=TestPage is re-written as
Folder/TestPage
This works fine on my local dev. machine on the Cassini server. But when its hosted in IIS (5.1 & 7.0) it fails to work, with the error as 404 Page Not Found.
I have written simple http module just to print Hello. but it is not working.
View 10 RepliesI am using Httphandler to access my pages. Have Loginstatus Control on the master pages.
OnLoggingOut for the Loginstatus control I am doing a Session.abandon()... But My session_end
does not get called in the Gobal.asax.I tried link button and everything. but when I take out the httphandler the Session_end gets executed in global.asax
I can handle the full session end on my own but is there any way to call Session_end in global.asax?
I have a bit confusion about the Http Handlers,Generic Handlers and the usage of those two.
View 1 RepliesI have an ASP.NET application with 5 .ashx HTTPHandlers that implement RequiresSessionState or IReadOnlySessionState.Upon calling the first handler I create a variable and store it in the session.When I call the next HttpHandler the variable is not available in the session object.I am use context.Session.I have a global.asax where I retrieve the sessionId.Is there a way to preserve session variables across HttpHandlers or does each Handler get its own session?
View 1 RepliesIn my new job, they have already written an httphandler to handle all the .aspx files, and they are not using asp.net's httphandler. Now, I want to use asp.net's regular .aspx httphandler for some web pages (.aspx files) in the project and the other pages need to be handled using their customized httphandler, i.e., 2 httphandlers for same file type (.aspx), how to do this?

I wants to url rewriting like as subdomain.
For example my website is website.com so that now i wants to url rewriting like
client1.website.com ,
client2.website.com,
client3.website.com,
clientN.website.com
In my website there are list of client whenever click on client my url like this
website.com/client.aspx?client=client1
website.com/client.aspx?client=client2
website.com/client.aspx?client=client3
website.com/client.aspx?client=clientN
Now i wants to url rewriting like as
client1.website.com
client2.website.com
client3.website.com
clientN.website.com
Also whenever once client is registered,After that client can directly open site
I have created my url rewrite handler and its working fine, but on live site i have IIS 6
and its not accepting the subdomain requests
when i type
http://website.com
it works fine but with
http://sub.wesite.com
i got the error Server not found
the project i'm working right now, client wants to make url seo friendly, if any event would enter from the admin section the url should show the name of the event itself.
right now it shows www.--------.com/eventdetails.aspx?id=879878
but the client wants www.---------.com/eventname/
the event comes dynamically every day.
I would like to perform HttpWebrequest every 10 min in my website. Right now it is performing onbutton click.

I have 2 asp.net apps, each on a different server and with its own SS2005 db.
What I need is to grab the data entered in a form in app1 and insert that "behind the scenes" into the app2 db.
I suppose I have to do a POST in app1 and intercept that in app2, but since I've not done much http handling yet, I could use some hints or even examples if possible.
The data to be transferred is all strings.
