HttpMethodBase.releaseConnection() finished download
Hi,
it seems that releaseConnection finishes the http-download until it is
complete. I don't want that. I'm looking for a way to close the
HttpConnection if the download wasn't completed yet.
I'm aware that one cannot "abort" a Http-Transfer without closing the
connection and therfor loosing it for keep-alive etc.
There doens't seem to be a way of closing the HttpConnection by using
the HttpMethodBase-Object. What should i try next?
Thx
Sven

Sven,
I've not tried this, but if you send a "Connection: close" header on the
request, the server should echo that on the response. If that header is
on the response from the server, the the "releaseConnection()" function
will (or at least it should) immediately close the connection, rather
than consuming the remainder of the body of the response.
Hope that helps.

Well, i had a short look at the source. Beside that the call to
releaseConnection() is delegeted from one Class to another, i cannot
find the place where the InputStream is read until EOF and i cannot
imagine how i should avoid it.

For semantic reasons I suggest an HttpMethod::abort() method. You will
need to create a patch against CVS HEAD. Because for the 2.0 branch it
is definitely too late for this feature.
Maybe we will even need a HttpClient::abortAll(), but then HttpClient
would need to know all the methods it is currently executing. That is
easy to implement however.

So what would you suggest how an abort should look like? For me, a
boolean paramter for the releaseConnection-method would be sufficient.
(releaseConnection() would be a shortcut to releaseConnection(boolean)
than).
I need this now, so i would try to implement a patch.

Hi Sven,
The only sure way to close the connection, at least for the moment, is
to get hold of the HttpConnection and call close() on it. The
following options come to mind:
- implement/override your own connection manager so that you have
direct access to the connections created.
- extend the Method in question and override the execute() method.
This will give the access to the connection that is being used to
execute the method.
Adding the ability to abort methods is planned for the 2.1 release, but
I don't think anyone has begun work on it yet. If you come up with a
good solution that you are willing to submit we would be happy to make
use of it.
Thanks,
Mike
