IHttpHandler problem

[Guest]

Hi;

I just wrote my first IHttpHandler and am having a problem. If the content
type is "text/html" then the below code works fine. But if it's "text/plain"
then my browser gets:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then
click the Refresh button, or try again later.


--------------------------------------------------------------------------------

Invalid at the top level of the document. Error processing resource
'http://localhost:3179/portal/ShowReport.aspx'. Line 1...

hi there
^

url is: http://localhost:3179/portal/ShowReport.aspx

code (App_Code\ShowReport.cs) is:
using System.Web;

/// <summary>
/// Summary description for ShowReport
/// </summary>
public class ShowReport : IHttpHandler
{
public ShowReport()
{
}

#region IHttpHandler Members

public bool IsReusable
{
get { return false; }
}

public void ProcessRequest(HttpContext context)
{

context.Response.ContentType = "text/plain";
context.Response.Write("hi there");
}

#endregion
}

web.config is:
<httpHandlers>
<add verb="*" path="ShowReport.aspx" type="ShowReport"/>
</httpHandlers>

???

Hi Dave,

I think the problem is that the response stream has not be eneded after you
finishing write out the content. then, the runtime may add some additional
http headers which cause the client browser fail to parse it. You can call
the response.End() to end the response stream after you finishing the
content outputing. e.g:

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Write("hi there");

context.Response.End();

}

Hope this helps.
