Hi Oleg,
Thanks for the reply, I figured as much.
I prefer to use expect/continue, which I actually do when the proxy
supports it, but in some cases unfortunately it doesn't and I must fall
back to preemptive.
What does seem strange to me is that HttpClient *does* retry the request
with the authentication header, as it seems to me that it is impossible
if the entity is not repeatable and some data is already sent. An
exception might be better?
Can you post a wire/context log of the session?
Oleg

Hi,
I'm trying to use preemptive authentication because I have a
non-repeatable (dyanimc) request entity. Currently when posting, this
goes wrong because I get a 401 Unauthorized but it has already sent
some of the data, and when it tries again with the basic
authentication credentials the post fails... (I've implemented the
writeTo(OutputStream) method on the Entity). I'm wondering by the way
how it can even do the request again because isRepeatable on the
entity returns false...
I construct my http client as follows:
final HttpParams httpParams = new BasicHttpParams();
HttpClientParams.setAuthenticationPreemptive(httpParams, true);
final DefaultHttpClient httpClient = new DefaultHttpClient(httpParams);
I searched the source for references to the
ClientPNames.PREEMPTIVE_AUTHENTICATION constant, but I couldn't find
any, so I'm wondering, is preemptive authentication implemented in
4.0 alpha 3 yet?
Sebastiaan,
There is no support for preemptive authentication at the moment.
Anyways, you'll be _much_ better off using the 'expect-continue'
handshake or making sure your entity is repeatable.
Hope this helps
Oleg
Or am I doing something wrong?

Sebastiaan
