dynamic POST

[Robin Becker]

Is there any way to get an IFRAME to do a POST without altering the
browser window's history?

I can achieve dynamic data loading using GET via the iframe's
contentWindow.l ocation.replace method, but that isn't suitable for large
requests.

You could submit some form in the iframe and let the CGI return the HTTP
status code
204
which means no response (body) and therefore I would guess the history
remains unchange.

Unfortunately, the idea is to actually get some response via a standard
call back embedded in the returned html/javascript.

Then I think you will have to live with a history being built up unless
you have an intranet with IE5/Win users and/or Mozilla users where you
could post data with XMLHttpRequest

So is that a standard in modern browsers? I can certainly do the server
side.

It is not a standard defined by the W3C or any other body publishing
standards for the Web but MS has implemented a COM based XML solution on
Windows that can be scripted with JScript in IE and Mozilla has tried to
implement the same API as close as possible in Mozilla browsers, see

for instance

After a bit of a google I discover quite a lot about this, but the
simple example at http://jibbering.com/2002/4/add.1 seems to add history
in Firefox/Mozilla, but not in IE 6. So the Mozilla XMLHttpRequest
object suffers from the same problem as iframe with post. At present I
can get by with my current strategy, but this sort of thing really bugs
me.

No, in my view that example is buggy, it doesn't work with Mozilla where
the script causes a script error (check the JavaScript console) and then
the form gets submitted normally and that is why you see a history being
built up.

you're right, but I still don't think I will change from my current
stuff. I will certainly bear this in mind in future though.

It predates the current Mozilla implementation and is written to the
specification, as I don't have a mozilla to hand, what's the error?

I know it would hit the old Mozilla bug of xmlhttp.send() erroring,
but I can't believe they've not fixed that one.

At least it falls back sensibly...

Cheers,

Jim.
