R

ra294

I am building a page that needs to recieve some parametes and return blank
page (empty response).
After I recieve the parametes I write:
Response.clear
Response.End

When I run the page I still get some html when doing "view source" in IE:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html;
charset=windows-1255"></HEAD>
<BODY></BODY></HTML>


How so return a completly blank page ?

Thanks

<HTML><HEAD>
<META http-equiv=Content-Type content="text/html;
charset=windows-1255"></HEAD>

I've tried everything I can think of, and it either still has those
lines appearing, or (in one case) it opens the file download popup box
and then downloads an empty file.

So given that it doesn't seem possible to do exactly what you've asked
for, how about telling us why you (thought you) needed this exact
behaviour, and maybe we can suggest some alternatives?

Yes, I can observe it. It is strange to me since I do have an application
where it works. It is in 1.1 though. Could be this changed between the
versions? I will try to investigate more.

Some more researching indicates that the possible culprit is the browser. In
my old working application the empty response arrives to an ActiveX control.
And if you get the response by some other means, not by the browser, it does
come empty.

If basic html markup isn't sent to a browser, no browser will be able to read the page.
A browser needs the basic html markup sent to it if you want it to read the response.

Juan,

Do you mean the browser substitutes a response that doesn't meet the minimal
requirements with the standard minimum? Or you are referring to the server
side?

Hi, Eliyahu.

I'm referring to standard html emitted by the server.
All the ASP.NET engine does is send HTML markup to the browser, as you know.

It doesn't send anything else, so sending nothing is impossible.
If there is to be *something* received by the browser, it *must* be enclosed within html tags.

Juan,

Browsers are not the only possible http clients. And http response is not
necessarily intended for displaying.

I have an application with an ActiveX control that http posts images to the
server. The control expects an empty response as an indicator of success.
Any non-empty response is considered as an error. So I made a page that
accepts images, saves them and returns nothing. Everyone is happy: the
control, me and the customer.

I think the browser is the one who inserts the standard empty html. Another
agent is IIS, but I don't think the IIS would bother to get involved into
the message content.

Agreed, but if a non-standard client was under consideration,
I'd expect that tidbit to be mentioned in the post, so I assumed
a browser was at the receiving end.

re:

It either is displayed...or is written into the source ( like scripts are... ).
Either way, html markup is needed, isn't it ?

Easily done that way.

I'll have to look into that. Do you have a reference ?
