we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.

have a web service that I'm trying to consume from a console app through http post. I receive a 500 exception error from the xmlstring parm being passed to the web service. Add the following to web.config of the web service. Although it is not working in debug in vs 2008 as well.

My web service uses .Net Framework 2.0. An e-learning application reads and updates an Access database in the web service via Http Post commands. I test the e-learning application and the web service using the version of IIS 7 that came with Windows Vista. I run IIS using localhost in my browser.
All works well. But a friend is having trouble running the same test with my files on her IIS 6 server. So I'm developing a checklist of issues in setting up an IIS 6 server to run a web service. I plan to include all possible causes of problems including permissions, accounts that are needed, etc. Are there resources to which I can go for this checklist?
I have a actionresult index method in my controller and a http post method for the same name. when i run the program the control should go to the http post method but by default it goes to the index method.

I'm trying to upload a file to an ASP 2.0 web service through HTTP 1.1 POST from a client-side application. If my web service function is declared as
<WebMethod()>
Public Function UploadFile(ByVal file as Byte(), ByVal fileName as String) as String
...
The test form says the request should take this form:
POST address_of_service HTTP/1.1
Host: <host>
Content-Type: application/x-www-form-urlencoded
Content-Length: length
file=string&file=string&fileName=string
How do I get my binary file data into that form? I've tried just converting the file data to a string and putting it in the body (file=<string_data_here>) but I get HTTP 500 errors back, complaining about not being able to convert it to System.Byte. I've got HTTP POST working fine elsewhere in my application with plain string parameters. Also, out of curiosity, why is it showing the file parameter twice?
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.

Maybe fiddler can be set up to allow this, I am not sure :-s If anyone knows, can you explain, or if anyone has used a tool on their local machine that can catch HTTP request/responses from the above code?
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
WS.PreAuthenticate = false;
WS.Credentials = System.Net.CredentialCache.DefaultCredentials;

I would like to manually send an HTTP 40x error code to client from a web method in c# asp.net web service.
Specifically I need to send 400 (Bad request) or 401 (Unauthorized).
I was thinking about the flow to look like:
if (a <= 0)
{
//send HTTP Error 400 - Bad request to client
return;
}
Is it possible? How?
I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?

we have a situation where we need to host two certificates on the same server and because we can't have two different certificates on the same server running off the same port we have assigned one certificate run through another port, which is 4443.

If I punch this into a web browser I can access it fine, however, if I create a web reference using this URL in Visual Studio (2005) it can create the web reference fine and it builds ok. But whenever I call a web method on this service instance I get a HTTP 404 page not found Exception.
Is there any properties I need to set on the web service object to get this to work? I'm confused as to why it's not working.

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.

If the service is defined in the current solution, try building the solution and adding the service reference again.
