Sep 21, 2010Is it possible to debug the init event from a http module? If I set breakpoints, they don't get triggered.

How Many Times Does HttpModule Init() Method Get Called During Application's Life
Jul 30, 2010Web application initialization is as follows:
As we know when IIS receives the first request for a particular Asp.net application resource, IIS creates an instance of a HttpApplication (defined in global.asax codebehind).When this new instance is created it's initialization happens that also checks all configured HTTP modules.All modules are then instantiated and put in the application's Modules collection (of type HttpModuleCollection)modules are looped through and their Init() method is called (when they register for request events)
As far as I understand it the above scenario happens when a web application is started/initialized (hence application start event).What happens with modules?
Are they (re)instatiated on each request or reused from the Modules property on each consecutive request while the web application is alive? As I understand IIS and Asp.net they are reused through the whole life of a web application.
If they are reused, can we assume that their Init() method is actually a pseudo event handler for application start event? The thing is we can't attach to application level events within http modules. But if they are being reused we could use Init() as application start event and do whatever we'd put in global.asax instead.
Question,Can we assume that module's Init() method is called only on application start event? Could we use this assumption to i.e. register routes for applications whose global.asax codebehind we can't change? web.config is usually accessible and we can change it the way we want.Would this actually work?
Additional info,We can check HttpApplication code and check its InitModulesCommon() method. This one actually calls Init() of each registered HTTP module. What is more interesting is that this method is only used by InitIntegratedModules() and InitModules() methods. Which are both used only in HttpApplication.InitInternal() method. This is the basis of my assumptions, but I would like to know whether someone has abused IHttpModule.Init() for application start event.
MVC :: Routes Not Picking Up With Another HttpModule Before The UrlRouting Module?
Jan 15, 2010I have integrated MVC into an existing web forms application which is an in house CMS system. There are two HttpModules. The first one is part of the in house CMS system and does url routing (for the web form pages) along with other required actions. The system creates routes from records in the database and if the page is an MVC Controller, the first HttpModule that belongs to CMS system does not do any more routing and the UrlRouting module should find the route and handle it. Locally it all appears to work fine with the built in Visual Studio debugger webserver. However when published up to remote webservers, all MVC pages result in a 404...even statically created routes on application startup. At the moment, the external webserver does note have remote debugging enabled so I'm stuck there. I am assuming it's related to the multiple HttpModules since standalone MVC applications do work fine on the remote webservers.
View 3 RepliesC# - How To Handle Application Start Event In Module
Jun 25, 2010I am writing an asp.net HTTP module which needs to read configuration data once from a local file (say config.xml stored in application root directory) and then based on configuration perform some processing on incoming requests.
Since there is no Application_Start/Application_init hooking available in Asp.NET modules, what would be the best way to handle the scenario. I am trying to avoid reading configuration file each time a request comes. Ideally, I want to read the config file when application starts.
I need to code this in http module only and do not want to use Global.asax

Bypass Existing HttpModule For A Http Handler?
Aug 11, 2010Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.

View 1 RepliesHttpHandlers / Modules :: Lowercase URL Rewriting With Http Module?
Jan 18, 2010Can anyone tell me if there is a way to convert all URL's to lowercase using an Http Module for URL rewriting? For example www.homeforhire.com/Home.aspx should be converted to lowercase.
I cannot use the IIS7 URL Rewriter because I need to perform database lookups as part of my URL rewriting.
I have researched this extensively but have not had any luck finding a solution.
The only alternative I can think of is to use a dynamically created canonical link in my page headers.

Aug 31, 2010I have come across this question several times, you need to do some performance testing (request process times, load times, etc) or track unhanded exceptions.

Why would we use one over the other? What are the pros and cons?

GridView OnRowEditing Events Not Firing When Using Unity 2.0 HTTP Module?
Jan 31, 2011I have an ASP.NET web forms site using Master Pages. It is using Unity as my IoC container. I have created an HTTP Module to build up the container using a couple of tutorials i found online. I need the dependency injection to work for User Controls and the only way i was able to get this to work was to hook into the Pages PreInit event as can be seen from the code below.
[code]....
I also have autoeventwireup set to true on the pages and master page. Can anyone shed any light on why the events are not firing? Is my Unity http module causing this to happen by dropping the event wiring? I can get this to work no problem in a basic example with no IoC involved.

Mar 16, 2011I am writing a custom HTTP module to implement user authentication and appropriate access rights.

Configuration :: Default Page Not Working On IIS7 With URL Rewrite Http Module
Jan 18, 2010I have the following setting in my web.config to redirect to a default page:
<defaultDocument>
<files>
<clear/>
<add value="default.aspx"/>
</files>
</defaultDocument>
For example when a user enters www.homeforhire.com they should be redirected to default.aspx (for operational reasons the user is then redirected to
www.homeforhire.com/home.aspx).
Instead an error is caught in the Rewrite module (which should not be activated). I am using an http module to perform URL rewriting.
It appears as if the default document setup is not working correctly, and the requested page ~/ is being sent to the Rewrite module, causing an error (which is then caught by my error handler and the user is redirected to the home page).
Entering www.homeforhire.com/default.aspx works correctly.
Can anyone tell me why the default document settings in the web.config do not appear to be working?

Debug Http 500 Errors
Jun 9, 2010I've developed a fairly simple web service which receives an xml string, validates it and passes it on to our internal database. This has been written to enable one of our clients to send us idocs from their SAP system. The trouble is that, although the web service works fine from a .net program, over the internet, the client's SAP system can't access it. They either get just an http 200 back (rather than the status code that the web service should supply) or they get http 500 'Internal Server Error'. I was wondering if anyone else has had issue's with ASP.NET web services from non 1qs`asp.net applications, or whether anyone can give me any advice on debugging http 500 errors.
