"No backend servers available" using httplib

[Henrik Lied]

Hi there!

I'm using a recipe found on ASPN [1] to upload some data to an
external server.

The request fails, and all I get in response is "No backend servers
available".

So I'm wondering: Is this a known exception-message in httplib, or
could it be an error in the requested external resource?

If it was, you should have a full traceback then.

or
could it be an error in the requested external resource?

From the recipe's code and the message, looks like you're connecting to
(or via) a proxy which fails to relay to the real server.

Hello Bruno,

The actual reason was quite a bit simpler: The receiving server
required a certain keyword to be first in the request - which I was
not aware of. So now it works - but it's not perfect:

Is there a way to stream the file content over the connection? The way
it works now, the whole file is loaded into memory, right?

It appears not, as the httplib uses sendall on the underlying socket.
