Why Is IHttpAsyncHandler Being Called Over IHttpHandler

Apr 13, 2010

I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest().

Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController.

I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.

AJAX :: Implementing IHttpAsyncHandler With Partial Postback?

Jan 20, 2011

I have a web app which implements IHttpAsyncHandler for handling web service calls asynchronously, done according to this web page:

[URL]

Now, my page is rather complex with many update panels, so when I initiate the AsyncHandler with BeginProcessRequest, the page does a partial postback, then when EndProcessRequest is called, another partial postback, everything is fine so far...

But when I navigate around my page and causes a partial postback between BeginProcessRequest and EndProcessRequest, nothing gets updated when EndProcessRequest is called...

In debug, EndProcessRequest IS CALLED in the server codebehind, but nothing updates clientside... I'm not even sure if it even caused a partial postback...

I'm a pretty big noob when it comes to this Async stuff, and I just followed the site above, so I'm guessing it maybe something behind the principle of how IHttpAsyncHandler works.

C# - Enable OutputCache With An IHttpHandler?

I have an IHttpHandler that I would like to hook into the OutputCache support so I can offload cached data to the IIS kernel. I know MVC must do this somehow, I found this in OutputCacheAttribute:

public override void OnResultExecuting(ResultExecutingContext filterContext) {
if (filterContext == null) {
throw new ArgumentNullException("filterContext");

Configure IHttpHandler In The Test Web Server?

Sep 24, 2010

I am trying to implement an IHttpHandler. I have defined an appropriate class but the debug web server (you know, the one you get if you hit f5 in Visual Studio) is responding with "Can't Display Page".I looked here http://msdn.microsoft.com/en-us/library/ms228090%28v=VS.90%29.aspx to learn how to configure the handler, and it seems there are different ways for IIS6 and 7. But the process is put something in the web.config and then set it up in IIS Manager. However, that is a deployment issue. I want to be able to run it in the test server, and I don't know how to do this second step in the test server.I put the following in my web.config:

<httpHandlers>
<add verb="*" path="*.sample"
type="MyNamespace.Code.HelloWorldHandler"/>
</httpHandlers>
HelloWorldHandler is the code from the link above (wrapped in MyNamespace.)

Can someone let me know how to configure this correctly for the development server?

C# - Downloading Multiple Files Using Ihttphandler?

Oct 20, 2010

I'm working on a reporting script which runs a number of reports (pdf) on button click. The reports are created on the web server then I'd like the user to be given the option to download the files. I have worked out the script for downloading one file from the server. But I'm not sure how to download multiple files? (there will probably be about 50)

After I run one report I redirect the user to a http handler script.

Response.Redirect("Download.ashx?ReportName=" + "WeeklySummary.pdf");
public class Download : IHttpHandler {
public void ProcessRequest(HttpContext context)
{

Save Data Between Calls To A IHttpHandler?

Mar 17, 2010

I have a IHttpHandler that acts as a source to a jQuery Autocomplete input field. In the constructor of the handler I generate an index that remains fairly static between request (needs to be rebuilt maybe once a day).How can I cache the the index between calls? Debugging indicates that the constructor is called for each request. I've set IsReusable to "false".

Ihttphandler - Create Handler Within Project

Jul 28, 2010

I want to create an HTTP handler within my project. To do this, I created a new class, and tried to implement IHttpHandler.

Each time I do this, I get the error 'End of statement expected'.

I know that normally you can create a new class library and create a class to implement a handler. But why is it not possible to do this in an existing web project?

C# - IHttpHandler Null Session (on Some Servers)?

Jun 25, 2010

I have an IHttpHandler that implements IRequiresSessionState. Everything works fine on most servers but there are 2 servers (one IIS 7.0 and one IIS 7.5) that give me null sessions. Aspx pages are fine on every server. I've searched for hours and failed to find anything that is not related to IRequiresSessionState.

C# - Handle RESTful-type URLs With An IHttpHandler?

Feb 7, 2010

First, I'm looking for a a small example of how to handle a series of RESTful URLs, such as /Account/{userName} and /Account/{userName}/Profile with a single HttpHandler. At this time, I'm not interested in embracing MVC or using the REST Starter Kit. Should I place the HttpHandler class in a Class Library? Should I publish to the root of the RESTful URL?

My second issue stems from the fact that my ASP.NET hosting is done through a web-hosting company. Will I need to ask their tech team to configure IIS for me? Is that normal practice?

HttpHandlers / Modules :: Implement Custom HttpContext For Each Request Under Class That Implements IHTTPHandler?

Aug 10, 2010

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.

How To Tell Who Called An HttpHandler

How can I tell from within an ASP.NET HttpHandler if it is executing because of a call to Server.Execute("myHandler.ashx")or because of the user linking directly to myHandler.ashx? (Besides using a querystring parameter).

The following code is executed when my app starts

StringValidatorBinder implements IModelBinder and simply throws an exception on BindModel, and I have a break line on there too. So, why does the following post method set "validation" to null and not call my model binder?[HttpPost]public ActionResult Create(string code, string description, StringValidator validation) {......}

Web Forms :: When Is Application_BeginRequest Called?

Sep 2, 2010

I have two versions of a website. One runs on IIS server on a local PC, the other runs on the ASP.NET development environment included on Visual Studio (localhost). Apart from that, the file stucture of both is the same, although only the one running on IIS works properly, and this seems to be related to the fact that the IIS version calls Application_BeginRequest() where the other doesn't.

I've looked at the differences between IIS server and the ASP development environment in: [URL], and it says that IIS and the ASP development server deal with static content in that for IIS in that on IIS static content does not go through the ASP.NET runtime like it does on the dev environment (but I'm not sure exactly what this means).

I've done a number of tests involving images, etc, and have noticed that when the image is of the form:

<img src="Image/MyImage.jpg...>

the IIS server version calls Application_BeginRequest(), but the visual studio development environment version doesn't.

However, if I change the above code to use:

<img src="<%=ResolveUrl("~/Image/MyImage.jpg")%>" ...>

it will call Application_BeginRequest().

In my case, it is necessary to call Application_BeginRequest because this creates a new path and calls
RewritePath().

The problem occurs when using links such as <a href="..." ...>, because if I use static content it won't call Application_BeginRequest() and the path won't be re-written. But If I change it to href=" %=ResolveUrl("~/...")%>" (for some reason, it will only call BeginRequest() if the path begins with a tilde ~), the path is re-written incorrectly.

I'm not really sure how to find out why the IIS version is calling Application_BeginRequest() from all the time (the callstack just says "external code"), or why it is calling it whereas the local dev server version isn't.

If anybody can explain this, or knows of any sites that go into this so I can master the basics, I'd be very grateful.

C# - Determine Which Tab An Action Was Called From?

Aug 27, 2010

The page I'm editing had three tabs, each tab contains a diffrent grid view which is populated by a search box with in the tab. Each row in the grid view has a check box. When a print button is pressed all records with a tick in the check box should be printed off. Then page then reloads but some of the content is missing due to the way the page has been coded. This is becuase some of the code is only called when the tab is clicked not on postback. Is there anyway that I change the following code so that it's called after postback? These are the functions that are causing the most problem.. I need them to be loaded for the correct tab on postback.. I can't do it for all three as the code takes forever to run in that case.

AddActionsToGridView(gvGlobal);
AddCheckboxesToGridView(gvGlobal);
{
if (tabconConsignments.ActiveTabIndex == 0)
{
dtGlobalIDConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "GlobalID", "", "");
//Global ID Tab
gvGlobal.DataSource = dtGlobalIDConsignments;
gvGlobal.DataBind();
//Actions
AddActionsToGridView(gvGlobal);
AddCheckboxesToGridView(gvGlobal);
}
else if (tabconConsignments.ActiveTabIndex == 1)
{
dtCreatedDateConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "CreatedDate", "", "");
//Created Date Tab
gvCreationDate.DataSource = dtCreatedDateConsignments;
gvCreationDate.DataBind();
tbCreationDateSearch.Text = "";
//Actions
AddActionsToGridView(gvCreationDate);
AddCheckboxesToGridView(gvCreationDate);
}
else if (tabconConsignments.ActiveTabIndex == 2)
{
dtAccountsConsignments = fGenerateTableSQL(astrPalletIDs, DateFrom, DateTo, ddlReqColDel.SelectedValue, "Account", "", "");
//Account Tab
gvAccount.DataSource = dtAccountsConsignments;
gvAccount.DataBind();
AddActionsToGridView(gvAccount);
AddCheckboxesToGridView(gvAccount);
}

if you want me to post any more code or any more info it's been a hard one for me to get my head around so I might of missed something out.

Application_BeginRequest Called For Images?

Jul 23, 2010

I've seen a few posts about Application_BeginRequest, but non seems to have my problem.

My Application_BeginRequest is being called for every image in my website.

The StaticFile Handler is enabled with * as the Path, but it's at the end of the list.

Is this the normal behaviour? Or should I add .gif, .jpg and so on on top of the list?

This is on my IIS7.5 Win7 Development Server. Didn't check it on the production server yet.

Update:
Setting runAllManagedModulesForAllRequests=false would help. But then the ASP.NET URL Mapping does not work anymore. I tried disable it just for the image directly, but that had no effect?

<location path="Resources">
<system.webServer>
<modules runAllManagedModulesForAllRequests="false">
</modules>
</system.webServer>

Executing Only The Last Function Called?

Feb 22, 2010

This is the setup in short. I have a big table. Everytime a cell get focus an asyncron call to the server is done (with PageMethods) and some data is returned and updates a infobox in the page.I have written code that makes it possible to navigate between cells with the arrow keyes.

The problem occurs when I shift focus fast through several cells in order to get to the cell I want. Every get-focus is executed and since the communication with the server takes about half a second it get quite irritating and not very user friendly.Ideally I would like to execute only the last focus event. But how? I cant know which event is the last one, can I?
