What ContentType for text?

[David Thielen]

Hi;

I am writing the output of a page directly using IHttpHandler,
IRequireSession State and if it is a text file I set
HttpContext.Res ponse.ContentTy pe = "text/plain". But when it displays I get
an error telling me it's not a legal xml file.

Any ideas?

Hello Dave,

As for the httphandler issue, I remember that you've ever posted a similiar
issue about rendering out some certain content in httphandler and encounter
error. Is this similar to that one? Yes, the txt file's mime type is
"text/plain".

I'm not sure about your detailed code logic, here is a simple test
httphandler which flush out some txt content:

=============== ====
public void ProcessRequest( HttpContext context)
{
context.Respons e.Clear();
context.Respons e.ClearHeaders( );
context.Respons e.ClearContent( );

context.Respons e.Write("Hello World.");

context.Respons e.End();
}
=============== ===

BTW, are you using the generic handler ( the ashx ) in VS 2005? If so, this
could be causing some problem since the generic handler may add some
additional content info internally that cause any non-xml/xhtml content
display error at client browser. You can test through a typical custom
httphandler (register in the web.config <httpHandlersse ction) to see
whether it works.

If you meet any further problem, please feel free to post here.

Sincerely,

Hi;

Still doesn't work. Here is what I am getting:

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

Here is my code:
public class ReportCreate : IHttpHandler, IRequiresSessio nState
{
....
public void ProcessRequest( HttpContext context)
{
....
context.Respons e.Clear();
context.Respons e.ClearHeaders( );
context.Respons e.ClearContent( );

string str = GetContentType( format);
context.Respons e.ContentType = str; // "text/plain"
context.Respons e.BinaryWrite(( (MemoryStream)r eport.GetReport ()).GetBuffer() );

context.Respons e.End();
}

Here is my web.config:
<httpHandlers >

Any ideas?

Thanks for your response,

This seems abit strange. I found that you still use the aspx extension for
your custom httphandler, have you tried using a different extension such
as *.txtfile to see whether it works. Also, if convenient, you provide a
simplified repro project so that I can test on my local side.

Use a .txt extension. Some browser, IE in particular, will ignore the
"text/plain" ContentType header, as older web pages sometimes used this
header for HTML pages.
