I am writing an ASP.NET application that generates CSV string and returns it using response.write. However, along with the CSV string, the output comes with other information I would like to get rid of (e.g. ASP.NET version, time-stamp) etc. How can I just get the CSV string and nothing else?

explain to me the concept of Request.Headers and Response.Headers in ASP.NET? Under what scenarios you use Request.Headers and Response.Headers?
View 1 RepliesUsing ASP.NET is it possible to make a request and get only response headers? I have to do a request to a big file, but I only need the response headers, i dont care about the content of the file.
I would like to know if there is something similar to get_headers from php (http://php.net/manual/en/function.get-headers.php).
I've build a MP4Handler. The Mp4 hander selects a correct file from a url.The system works if you work with 'normal' mp4 files.But the problem is the MP4 files are genrated by another program, so i think there's the problem.Right now i returned a test file, then it woks great!Do i return the other file, i get a 412 error if i use it in IE (he shows a 400 error because i deleted the 412 error in the IIS i thought maybe that solves the problem). In IE it doesn't work, but in firefox it works great!In my Fiddler result, the first movie (guid url) is from firefox, and works great. The second with the text/html result (selected row) is from IIS.How can i solve this problem?Or is this the problem?:This entity tag is not recognized by IIS. It only affects version 7.0 of the IIS software.From: http://www.pc-library.com/errors/error-code/412-0x19C/ As coding i use this as base: http://dotnetslackers.com/articles/aspnet/Range-Specific-Requests-in-ASP-NET.aspx I changed The GetRequestedFileInfo with:
public override FileInfo GetRequestedFileInfo(HttpContext context)
{
return new FileInfo(context.Request.PhysicalPath);
}
In my application I need to set a http response header. I'd like to do this in web.config. but I dont'know if this is possible and I can't find it on Google. Solution Finally, after a long search I found the solution. Create a class with this code:
public class myHTTPHeaderModule : IHttpModule
{
#region IHttpModule Members
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.EndRequest += new EventHandler(context_EndRequest);
}
void context_EndRequest(object sender, EventArgs e)
{
HttpResponse response = HttpContext.Current.Response;
response.AddHeader("Content-Language", "*");
}
#endregion
}
(Don't ask me why to use this event, but it works..) Now add a line in web.config in the HttpModule section:
<httpModules>
<add type="namespace.myHTTPHeaderModule, assembly name" name="headers" />
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</httpModules>
I read somewhere the you can't remove response headers once they've been added. Given that, I'm wondering where in a standard ASP.NET web forms application do response headers get added initially. For example, these:Date Fri, 23 Apr 2010 16:25:56 GMT erver Microsoft-IIS/6.0 X-Powered-By ASP.NET Cache-Control privateAnd can I stop it from happening? Do subsequent headers override old headers?
View 2 RepliesWhen I try to access Request.Headers I get a "This operation requires IIS integrated pipeline mode." error.
Is there really no way to view the response headers in .net with IIS6?
In IIS 7.0 integrated mode after deleting all headers with Response.ClearHeaders() IIS would add some other headers like Server and X-Powered-By which reveals good information to hackers. How can I stop this behavior (consider I still need to add my custom headers) ?
View 2 Repliesas subject, how can i read Response Headers inside an httpmodule?
i need the "Content-encoding" header value.
In the web app (C#, ASP.NET) I am working on at the moment, the value in Request.Headers["Referer"] can determine things like custom style. I have created a custom page with a drop down menu to test this functionality. So when the selected index changes, the value selected should be set in the Request.Headers["Referer"] then will be redirected (Response.Redirect), the receiving page will then pick up the value in Request.Headers["Referer"] and adjust the styling accordingly. However I haven't been able to set value for Request.Headers["Referer"]. Is it possible at all?
Website 1 sets the value in Request.Headers["Referer"], e.g. www.xyz.com and before doing Response.Redirect to www.website2.com
Website 2 picks up value in Request.Headers["Referer"], in this case www.xyz.com and do what it needs to do, i.e. styling etc.
I'm trying to return an xml string from a IHttpHandler to a like this: context.Response.Write(xml); When I receive the response in my .aspx.cs I try to load the document as follows: var xml = XDocument.Load(xmlString); but I get an Illegal Characters in Path error message. I've also tried
context.Response.Write(context.Server.HtmlEncode(xml));
and
var xml = XDocument.Load(Server.HtmlDecode(xmlString));
but I get the same message. Is there any way I can return XML from my IHttpHandler?
I have never work with a repeater and after a lot of research I got to the conclusion that this is the control I need to use for what I have to do. I need display data but I will need 2 headers and after some sort of amount of records the headers will repeat again. In this page you will find an example of what I'm trying to do http://ratings.fide.com/view_source.phtml?code=45276 I don't know if a repeater is the right control but i thin it is.
View 3 RepliesI am trying to the following to return xml response from an http request
Code:
Try
Dim id As String = Request.QueryString("id")
Dim xmlOut As String = ""
cn.ConnectionString = "Data Source=192.168.1.2;Initial Catalog=db;Persist Security Info=True;User ID=sa;Password=pass"
dad = New SqlDataAdapter("select * from tbl where id = '" & id & "'", cn)
ds.Clear()

Is there some other way to do this without having to resort to writing the xml to a temp file on C drive and reading it again to display the output ?
An external server sends incoming SMS messages converted to HTTP requests into my sometimes very time-consuming .aspx page. If no response is returned to the external server in 20 seconds, this is considered as an timeout and the same message is sent to my aspx page again (and maybe again....The optimal solution for me would be that the aspx page reads the incoming message (as an HTTP request to the aspx page), starts the processing of the message in another thread, and immediately renders response back to the external server. The external server has no interest in other stuff than the HTTP status (normally 200). When the processing of the message is completed this results in an entry into the log file of the application.

I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:

This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
