Loopback - Why Can't Make An Http Request To The ASP.NET Development Server On Localhost
Apr 5, 2010
I have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File->New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result:
C:Usersfarmercs>telnet localhost 54752 Connecting To localhost...Could not open connection to the host, on port 54752: Connect failed I can see in the system tray that the server thinks it's running, and a netstat -a -n command shows that there is indeed an active TCP listener on that port.
This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit.
I also tried to hit the port using the server name itself (http://mycomputername:54752) but with the same result. So, what could be blocking me from connecting? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?

i have a couple of xml files in my asp.net web application that i don't want anyone to access other than my server side code. this is what i tried..
<add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler" />
i wrote this inside the <httpHandlers>
it works well on the localhost but not in the server... the server without any hesitation displays the xml file... i have no idea how to proceed...
Update: the server has IIS6, windows server 2003

I'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.
[Code]....
And got the error saying "Operation is not supported on this platform".

I am currently writing a C# web service which has several methods, one of which has to receive HTTP POST requests. The first thing i have done is alter the web.config file in the web service project as below.
[code]....
But when i run this i get "The remote server returned an error: (500) Internal Server Error". If i remove the parameter, by removing the stringbuilder and byte code, as well as having no parameter in the web service, it works. So it is obviously a problem with the parameters. I actually want to send more data, and was using a string[] parameter in the web service, but this also failed.

There is one page which is actually a streaming to The Axis IP camera which spits MJPEG output.It requires user to log in with the user name/password promp on browser .I am using this stream to show video directly on a web page.It shows video correctly but asks user to provide correct user name and password set for the camera,I tried to logging in to this camera on server side using HTTP requests and then I realized I authenticated server request not the browser the end user is using.
So what I want is a method server side or client side, that can allow me to log-in to camera automatically when my end-users visit this page.I am using asp.net with c# 2005

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.

I created aMicrosoft.Reporting.WinForms.ReportViewer with a window application. It worked fine when I was in net A with domain A. My application is now moved to net B with domain B. However when I login to my computer I still login netA with domain A, userID and password for A. I then use a A/B switch to switch to net B to run my application running ReportViewer (no login directly to B). But when I run ReportViewer I got errors like below.
The request failed with HTTP status 401: Unauthorized.

I created a simple web service in VS2010 (C# - XP Professional SP3 development computer -- running .Net 3.5/4.0) that just does the basic "Hello World" and changes Temperatues from Farenhet to Celcius functions and ran fine in VS2010. I then created a directory in C:Inetpubwwwrootwebsvcvs10a (of the same development computer). In the localhost IIS I converted this to an application directory (properties/create application). I tried to deploy my web service here using the publish wizard of VS2010 but was getting errors stating that the URL was not in the correct format, so I decided to just copy myService1.asmx, Web.Config, and the bin folder (which contains the compiled assembly) directly to C:Inetpubwwwrootwebsvcvs10a. Then from the localhost IIS I tried to browse myService1.asmx and received the following error:
Configuration Error
Description:An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Version Information: Microsoft .NET Framework Version:2.0.50727.3615; ASP.NET Version:2.0.50727.3618
--I tried changing the targetFramework to 3.5 in web.config, but that did not fix the problem. I then removed the targetFramework attribute from web.config and then got this error message:
Could not load file or assembly 'myVS2010Websvc' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
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.
Exception Details: System.BadImageFormatException: Could not load file or assembly 'myVS2010Websvc' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
What can I / should I do to resolve this problem so that I can deploy this web service project to localhost -- don't I already have .Net 4.0 runtime on this machine? It is the same machine that is running VS2010.

I 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();

My application separates users by company identifiers in the URL: company1.app.com, company2.app.com...I am testing on my local PC with a request such as: company1.localhost.com. However, my request.Url.Authority still shows "localhost.com" instead of "company1.localhost.com". In fact, the prefix of 'company1' does not show anywhere. Is this a bug or a feature?
It's worth noting that I added to the host file an entry for "comapany.Blah -> 127.0.0.1". When looking at Request.Url.Authority it STIL shows localhost...

I'm using Request.Files to obtain a file that the user is uploading on my web page.I noticed that if I use the filename property in IIS it gives me a path + filename, however if I run in cassini it only gives me the filename no matter what directory I use.Why is this? And, is there a way to just use the filename when in IIS?

For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?

I have developed the WCF service as follows.
1) Service Contracts in a project
2) Data Contracts in a project
3) Finally adding the reference of service contract project in a Hosting project (Console Application) with complete configurations.
I am adding one more windows app project as a client.When i am trying to add the service reference using the address "http://localhost:8000/Tasks", VS 2008 displays the below error.
There was an error downloading 'http://localhost:8000/Tasks'.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
Metadata contains a reference that cannot be resolved: 'http://localhost:8000/Tasks'.
Could not connect to http://localhost:8000/Tasks. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
If the service is defined in the current solution, try building the solution and adding the service reference again.

I've written a small MVC application and am having trouble deploying it to localhost. I use the publish feature when I browse http://localhost this is what I get: HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this dir A sample aspx page is rendered correctly.
I've tried the aspnet_regiis -r I've made sure ASP.NET is installed in Windows Features. The web platform installer tells me MVC 2.0 is installed. I did install VS2010 first and then IIS so I suspect that maybe causing problems but in the past aspnet_regiis -r has fixed that.

I am developing a facebook application in asp.net using the facebook developkit downloaded from [URL] website.
I am practicing a sample application in SDK 3.02samplesIFrame.
They have give an attribute called RequiredAttribute = true in IFrameMaster.Master.cs, which will access the basic information.
But I want to request for extended permission in the same screen itself.
For that i have used this.RequiredPermissions = new List() { Facebook.Schema.Enums.ExtendedPermissions.publish_stream, Facebook.Schema.Enums.ExtendedPermissions.offline_access };
But there is no use.
Is there any way to do it.
