I have created a chart control webpart and trying to deploy onto sharepoint2010 page. I am able to add the standard webparts. When it comes to the webparts related to chartcontrols I get the following error.
no http handler was found for request type 'get'.
I have a new virtual server, subsite. but I get the feeling I may be still be inherting from the root config! Even though I have included <clear/> within both the <connectionString> and <httpModules>.
The main website works (web1) along with one of the subsites (web2) however the 3rd subsite (web3) gives the below error.
e.g.
http://web1
http://web1/web2
http://web1/web3
Gives the following error :
No http handler was found for request type 'GET'
Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

View 3 RepliesI try to add a new web api to my .net application and place it on Azure (where all my APIs are).
The new API is getNumbers:
public class GetNumbersController : ApiController
{
[HttpGet]
public List<string> GetNumbers(string planeType)
{
...
} }
For some reason i can't access it. when i type the url [server]/getNumbers i receive:
<Error>
<Message>
No HTTP resource was found that matches the request URI 'http://aeronexus-we.azurewebsites.net/GetTailNumbers'.
</Message>
</Error>
Of course that all my other APIs build the same and are accessible
I even can't see my new API under
[server]/help (where i can see all the others)
Locally I can access my new API
The routes is:
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "{controller}/{action}/{id}",
defaults: new {id = RouteParameter.Optional})
I am getting an error as "The request failed with HTTP status 404: Object Not Found." earlier I used to get the output for this source code.
from the last two days i am scraching my head, i could not solve the problem, but i have traced the problem, that is when i tryed to open 'http://localhost' from my explorer i am not gettting the IIS help page.
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
View 1 RepliesBackground:
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
Response.OutputStream = WebRequest.Create(FacebookUrlForThumbnail)
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?
When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.

View 4 RepliesI 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).
I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
I'm just reading about implementing my own HTTP handler for ASP.NET 4.0 and IIS7. This looks really cool. I want special processing for ZIP files and it seems like an HTTP handler is the perfect solution.However, what's giving me trouble is that the handler must be in a separate assembly. So how can I access the rest of my application from this assembly?Specifically, I'd like to determine if the user is authenticated and redirect them to the login page if they are not. But User.Identity.IsAuthenticated, etc. will not be available from my handler.(Yes, I know there are ways to approach this without an HTTP handler but they don't seem appropriate for my specific needs.)

View 4 RepliesI'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my 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"/>
<add verb="GET" path="processTask*" type="MyHandler.ProcessTaskHandler, MyHandler"/>
</httpHandlers>
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/>
and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
Here's what I want to do:
I've created a class library project
and this has a class implementing
the IHttpHandler interface. Let's
call this class ZipHandler. Let's
say the namespace is Zip.
I want that whenever any Http
request comes for a zip file, my
ZipHandler should handle it,
regardless of whether the request is
to an Asp.Net application or a
normal virtual directory.
Queries:
Is it possible (it should be given
the hype about integrated pipeline
etc. in IIS 7)?
How to do it?
we know that we can access previous page url in asp.net by using Request.UrlReferer. So i also used this property to access prev page url in my web application. But my problem is that all works fine in http:// and problem starts when move web site in production server with https:// instead of http:// So can any one have idea what to do to get Request.UrlReferer in https:// ? problem occurs all the other browser not in IE ( problem in : Mozzila,Safari,Chrome....)
View 3 RepliesI'm trying to develop a Web application that sends requests it recieves to another server. Basically, my application will work like a proxy sending requests and responses to client and real server. I'm using HttpHandlers to capture all requests coming to server and using a class implemented from IHttpHandler, I create another request to my target server.
So far, I tried:
[Code]....
which got me the first page I request, for example when I request login page, I see it, but I can't see css or images(basically because it writes css and image files to page with context.Response.Write) also, since I did not get server variables I can not log in to my server, I keep reloading login page when I click login button.Then I tried changing the Host header of the first request I got thinking I could do a request with same request headers.

And got the error saying "Operation is not supported on this platform".
I am new to this topic. SO please look over my stupid mistakes. I have web application and its virtual directory path is as followshtpp://localhost/TxtXmlImggHandler/This root has three pages one for text, one for xml, one for images. Actually these pages call three different handlers. I had no problem when I send/receive some data to HTTPHandler for processing, had no problem when I request xml file from HTTPHandler.Now I am trying to get image from HTTPHandler, but no luck. All my HTTPHandlers are sitting in root of my web application

I have an VS2010 ASP.NET 4 web site app, to which I added the new Chart control.
When I deployed it to our web server, we get a" Internal Server Error 500." message.
I noticed that the following lines were added to the web.config since the last release, related to the chart control:
<system.web>
<httpHandlers>
<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
validate="false" />
</httpHandlers>
If I remove this added code from the web.config, the site works--Except for the charting functionality.
How do I get the site and the chart page to work?
This is not an issue on IIS versions < 7.
