I have a System.Web.UI.Page page which receive both POST and PUT HTTP requests.
Reading a POST data through the Request.Form field is fine.
But how can i get PUT data? Request.Form field is empty.
Is there a way to access the raw request? or better: The PUT data?

I have a web page (Provider) that creates an XML file to be send to the Requester in this fashion:
1. A Requester page needs to send an XML file to the provider page
2. Provider will read the XML file to authenticate the request
3. Provider will Create an xml file with some data.
4. Provider will send the xml file back to the Requester.
Can anyone provide sample code for both the Requestor page (step 1) and the Provider page (steps 2 & 3)
can i read from the viewstate in the control render method ?
(because i read an article on msdn that said that after the preRender event is fire you can't read from the viewstate.)
and is the answer would change if i said that i am reading from the view state something that is not related to server control ?

View 3 RepliesI am having problem redirecting error when error is http 500 or http 403 locally running this site there is no problem it gets redirected to my errorpage.aspx. But when deployed at server, it does not get .tried putting try and catch in page_load and in global.asax and I have set Application_Error to redirect to that page and also set <customErrors defaultRedirect to that page also
error
statusCode="500"
redirect="/errors/errorpage.aspx?error=500"

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 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

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.
View 4 RepliesIn my current project, my client application first talk with the server and the server returned an upload url for me to upload a file, the url looks like this: [URL] Then I want to use HTTP PUT method to upload the local "c:pesult.cab" to the above loacation. How could I do this? And could anyone give me a detailed description about the whole uploading mechanism? When I use a ASP.NET upload control, I just click the browse button to locate my file and click submit, and on the server side, I just call the SaveAs() method of the upload control. Here is some code:
protected void UploadButton_Click(object sender, EventArgs e)
{
if(FileUploadControl.HasFile)
{
try
{
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
StatusLabel.Text = "Upload status: File uploaded!";
}
catch (Exception ex)
{
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
}
}
Who is responsible for reading the file and sending it? What happens when I call FileUploadControl.SaveAs() method? Does the server pull the file from client, or the client push the file to the server? I know HTTP is text based, but my result.cab is not text, so is it Base64 encoded before being sent? How does HTTP PUT method work? Is it a client side push, or a server side pull? Or interaction of both like some kind of handshake?
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.

my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production).
It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings.
I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often).
I was considering storing the connection string in Application["ConnectionString"].
[code].....
I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons?
I have two model classes:
public class UserModel
{
public Guid Id { get; set; }
public string EmailAddress { get; set; }
public string LoginName { get; set; }
public string Password { get; set; }
}
public class GroupModel
{
public Guid Id { get; set; }
public string Name { get; set; }
public List<UserModel> Users { get; set; }
}
I created a View (Create.Aspx) by inheriting GroupModel class.

It is generating only two fields (Id, Name) in my aspx view. Also I am able to get the form data in the Model class object in ё[HttpPost]ё request which contains the data for ID and NAME field in controller.
[HttpPost]
public ActionResult Create(GroupModel groupModel)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
How can I get the data in List<UserModel> object? I am thinking to Put a List control with checkboxes containing Users. Then catch them using FormCollection object in controller.
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?
