WCF / ASMX :: Web Service Fails - 400 Bad Request - Only Certain Connections
Feb 21, 2011
I've got a web service on a server with valid IP and valid DNS entries. I'm using an asynchronous thread in a WPF .NET application to access methods from that web service. Under normal connection conditions, for almost all users, the connection and method works fine. Under a very specific condition - Verizon Aircard being used to connect, no VPN connection to the company through SSTP, on a PC with Forefront Client Security installed - the web service will return a "HTTP Error 400: Bad Request" error to the user. If the same user on the same PC connect their VPN connection, the method works flawlessly.
I have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
have a working ASP.NET 3.5 webservice that accepts standard POST requests using an encoding type of application/x-www-form-urlencoded. I then added a method which needs to accept an uploaded file. We change the encoding type of the request to multipart/form-data so that we can get the file data and now we receive the following error:System.InvalidOperationException: Request format is invalid: multipart/form-data
I am consuming a Web service passing it an XML string. The WS is querying a SQL Databse and returns an XML string. It all works fine from within Visual Studio 2010. Running the website from the browser, I receive the following error when calling ws.method "RQ.ProcessRequest(XMLOut, XMLIn)":
INNER EXCEPTION: System.Exception: The login failed when connecting to SQL Server SOMTSNAV01
[Code]....
Is there some additional credentials I need to pass to the WS? Is there anything that needs to be done on th WS side to ensure login does not fail? Ideas anyone?
I have an ASMX web service which, in turn, creates a Service Reference which ultimately calls a third party web service. So, in essence, my ASMX is acting as a proxy to the thrid party service. This works fine on my development box.When I deploy to a target server and call my ASMX web service, it fails with an object instance not set error. On closer inspection, it looks as if the failure is in the line of code which creates an instance of the Service Reference - DIM XXX as new ServiceReference.I'm guessing that something has gone missing in the deployment, but can't see what.
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

Please help me to encrypt this request using the X509 certificate. Am having a certificate with public key and with subject "My Calculator"and also decrypt the result with the private key "abcdef" and with subject "My Response"
for the past couple of days i am facing an issue where the first call from my ASP.NET 4 application (VS 2010 Web Site) hosted in IIS 7 to an XML web service is dead-slow. subsequent calls are fast until the AppDomain is restarted.
I have tried all solutions related to pre-generating the serializer assembly but nothing worked. Anyway THEN I was sure it is an IIS-only issue because if i consume the xml web service from a console .net application then all the calls are fast. its even fast from an ASP.NET web site NOT hosted in IIS instead running on the development server. SO clearly the problem is there only when my app is hosted in IIS.
I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
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 implementing a Google like search box in my asp.net application. Each keypress in the box sends an Ajax request to IIS webmethod that queries the txt and return matches - works pretty cool. However, on loading up activity (e.g. 300 users), I'm getting errors that my 100 Pooled connections are used up. Now I'm rethinking that perhaps opening/closing a db connection on each keystroke may be too much. How would one architect this differently, or insure that the connections are reclaimed really fast. I'm have the 'using' construct for connections to insure it is closed. The concern is GC may not be reclaiming them fast enough?
How would google handle such a large open/close cycle.
when i am adding service reference the Following erro shows Up..where as the same works on the Other machine. The url when tested in Internet explorer works but only while adding shows the error. The request failed with HTTP status 403: Forbidden. The HTTP request was forbidden with client authentication scheme 'Anonymous'.

if i have the web application with many pages like add order page, edit order page, and delete order page actually they also interact with the Sql Server 2008 and i also create web service page call Sales_Service.asmx. i know just i need to put something like query into Web Method in Sales_Service.asmx but i have a lot of queries, i don't know which query i should put into it and how the web page call the Sales_Services.asmx
i tried to use external assembly in my web service method (Web service is worked in LAN). This external assembly in their own internals use TcpClient to access to external IP address. But unfortunally. Creation of TcpClient fails.

I have a web service hosted on a web server, I invoke the web service using jquery ajax.
The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain).
I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').
One of our client uses squid proxy and tries to connect to our asmx web service(which is deployed on our server over internet) via our windows application. But windows application fails to connect to our web service and gives below error.."This method call needs the custom bla bla.. " Soap ExceptionProxy (squid) shows this error:127.0.0.1 - - [10/Aug/2010:14:35:55 +0300] "POST http://abc:83/service.asmx HTTP/1.1" 500 759 "-" "Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.4927)" TCP_MISS DIRECTWe have used soap header security and we are also passing soap header credential while calling the service. Application runs well at our end but can anybody guid me, what could be the problem ?
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
I am looking to incorporate web service into my application but am running into a problem. The following line of code in FwkComm.js document generates the following error: Microsoft JScript runtime error: 'FwkService' is undefined.
