Thats actually what the apache commons-httpclient library does. One has
to explicitly enable the use of Expect. Thats how I found the
bug/problem btw.
However, I have no clue at all in the HTTP / java.net area so I cannot
provide a patch which correctly would address such a change.
Well you understand it well enough to have created your first patch.
Beside that,
if it would be done the same way as this patch it would also introduce a
public method in the implementation class of URLConnection to enable Expect
header usage.
Not true: java.net.URLConnection.addRequestProperty("Expect",
"100-Continue");
