Difference Between HttpApplication Class And IHttpModule?
Jan 31, 2011What is the difference between HttpApplication class and IHttpModule? Are they both same or different?
I see articles that mention the same events in both the classes.

C# - Accessing HttpApplication.Application Variables From A Class?
Jun 9, 2010I set up various global parameters in Global.asax, as such:
Application["PagePolicies"] = "~/Lab/Policies.aspx";
Application["PageShare"] = "/Share.aspx";
Application["FileSearchQueries"] = Server.MapPath("~/Resources/SearchQueries.xml");
I have no problem accessing these variables form .ascx.cs or .aspx.cs file -- ie. files that are part of the Web content. However, I can't seem to access 'Application' from basic class objects (ie. standalone .cs files). I read somewhere to use a slight variations in .cs files, as follows, but it always comes throws an exception when in use:
String file = (String)System.Web.HttpContext.Current.Application["FileSearchQueries"];

Way To Override And Inherit Default HttpApplication Class From Global.asax
Oct 19, 2010am currently working on a web application, whereby I want to add code to the Application_BeginRequest method of the Global.asax file, without adding code to the Global.asax file, which sounds a little crazy, let me explain a bit more.If anyone has ever developed in sitecore before, they would have seen that the Global.asax file has empty methods, however it has 'using Sitecore;' and the global.asax file provided does not inherit from System.Web.HttpApplication.

C# - Implement A .NET Event On An IHttpModule?
Nov 7, 2010I've declared an event on an HTTP Module so it will poll subscribers for a true/false value to determine if it should go ahead with its task of tweaking the HTTP Response. If only one subscriber answers true then it runs its logic.
Are there potential pitfalls I'm not seeing?
public class ResponseTweaker : IHttpModule {
// to be a list of subscribers
List<Func<HttpApplication, bool>> listRespondants = new List<Func<HttpApplication, bool>>();
// event that stores its subscribers in a collection
public event Func<HttpApplication, bool> RequestConfirmation {

</httpModules>
and an instance of it is sitting in the pipeline.
From the perspective of a caller (e.g. from the Global.asax.cs file), how should I get a reference to that module instance?

Use HttpApplication State In A .NET Console App?
Dec 10, 2010I need to quickly write a test console app for testing purposes.This app is basically the console version of an ASP.NET app.The original ASP.NET app makes use of the global Application object for storing global data.How can I get the same functionality of the Application object in my console app? Can I declare an HttpApplication object directly and use it?NOTE - this app is just for debugging some issues, not production code, so I'm ok if it's not "best practice".

View 1 RepliesC# - Accessing The Form Collection In An IHttpModule Causes Event Handler Not To Get Called On Default Page
Mar 18, 2011I've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.

HttpHandlers / Modules :: Httpapplication Module Accessing Session Variables?
Jul 2, 2010I hope I am posting into the right area... I want to know if you can access a session variable from a HTTP Module in IIS 7. Here is the scenario, I want to access the session values (i.e. User Object) from a HTTP Module. I have read oodles and tried many things but to no avail. I guess the application uses Forms authentication to authorize a logon to the site. I want to monitor the url that is submitted... RAWUrl property and if they are going to a certain page I want to grab their user object from THEIR session and validate them for access to that page. I want to use a httpmodule for this. The long and short of this is "Can I get access to session variables from the request from the httpmodule code behind? If I can, could you beso kind as to show me a working sample... I have tried many permutations on this using httpapplication, context and so forth and I can't seem to get access to session variables that would belong to the users request. it this possible?
View 1 RepliesDetermine If A HTTP Request Is A Soap Request On HttpApplication.AuthenticateRequest
Jan 21, 2010I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<webServices>
<protocols>
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
