Old HttpHandlers And HttpModules Elements Needed In IIS7?
May 9, 2010I'd like to clean up the web.config and remove unneeded XML.
A default ASP.NET 3.5 web application has the follow elements in the web.config:
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
</httpHandlers>
<httpModules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</httpModules>
When running under IIS7, which has modules and handlers being registered under the system.webServer element, is the configuration above still needed?

Decoding The Web.config Httpmodules?
Jan 28, 2010I recently started learning about HttpModules and made my first one. I was wondering if someone could explain why some modules in the the web.config include a lot of extra info and others do not.
example: not much info
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
example a lot of info
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
What is a publickeytoken, version, culture. Do I need to do anything special to use those?
Order Of Execution For HttpModules Determined?
Mar 11, 2010Suppose that both FirstModule and SecondModule handle the Application_BeginRequest event. Will it execute in the order defined in the web.config?
<httpModules>
<add type="MyApp.FirstModule, MyApp" name="FirstModule"/>
<add type="MyApp.SecondModule, MyApp" name="SecondModule"/>
<add type="OtherApp.OtherModule, OtherApp" name="OtherModule"/>
</httpModules>
Are there other ways that the order can be specified?
Are There Any Guidance Resources Available In Regards To Error Handling INSIDE Of HttpModules
Jan 27, 2011I attempted to find any information in regards to best practices of handling errors inside of a HttpModule unfortunately I can't seem to find any information on Google in regards to this.
All the information I've found all pertains in how to use the global.asax or a custom http module to log errors which is completely not pertinent.
Edit: Clearly this question has been misunderstood. I am seeking information regarding software patterns that are employed to prevent a HttpModules from faulting, triggering custom errors redirection, and faulting again causing infinite exception chains until IIS shuts down the thread entirely.
This however is very nontrivial since the HttpSessionState collection can't be depended on for the life cycle of HttpModules. Since error conditions have already occurred it would be improper to expect that I could read the ASP.NET session cookie to get an identifier that I could store user specific data in the application cache. Storing data in the HttpRequest.Items collection would be pointless since that in no way exists across multiple requests.
Does 1.1 Support Generic HttpHandlers
Apr 14, 2010I 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 RepliesAre HttpHandlers Reinstantiated Every Request
Dec 31, 2010I'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?

View 2 RepliesSet IsReusable To True In HttpHandlers?
Jan 13, 2010I'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?
