Hi all,
I'm using httpclient-4.0-alpha2.jar and httpcore-4.0-alpha6.jar to download a
zip file from a server. My problem is when I try to download part of the zip
file (using Get request, Range header), and the server replies with a '302
Found' response, httpclient automatically submits a new GET request (this is
what I expected) but the Range header is not used for the new GET request. As a
result, I receive a response '200 OK' instead the response '206 Partial
Content'.
My question is if this behavior is correct or a bug? I don't find any documents
from Internet about the expected behavior in this case, but I believe that when
httpclient follows a new location, it should send the headers of the old
request to the new location.
Attached is my sample program (Main1.java) and the log printed by httpclient
4.0-alpha6 (log.txt).
Thanks for your help.
Regards,
Thai
