REST: eternal HTTP status 204
I'm trying simple python program to using ActiveMQ via HTTP.
I managed to send message via HTTP/POST, but have problems getting them via
GET (or DELETE). While first request receive message (with HTTP status 200),
all other requests has status 204 (not modified?) and no body after long
delay (~5 seconds). It start working after restaring amq - but only one
message again. What I'm doing wrong? Any advices, please? I see the same
behavior with web browser when using "send/recieve message" in demo so i
don't think it is my program.
I tried 4.1.1 and 5.0 snapshots - same behavior. And using web browser JDK
1.6, Ubuntu 7.04. amq working under root.

def SendMessage(queue, body):
url = BASE + "message/" + queue
print "[%s] -> %s" % (body, url) # "destination": queue,
body = urllib.urlencode({"type": dtype, "body" : body})

url = BASE + "message/" + queue + "?" + urllib.urlencode({"type": dtype,
"timeout": 1})
print url,'->'
headers, body = client.request(url, method, None, None)
print 'STATUS:',headers["status"]
return body
queue = "queue22"
SendMessage(queue, "test message2")
SendMessage(queue, "test message3")
SendMessage(queue, "test message4")
sleep(1)
print GetMessage(queue, "GET")
print GetMessage(queue, "GET")
print GetMessage(queue, "GET")

Unfortunately no,
the web client that do all the work is tied to a HTTP session.

Hello Dejan,
Thank you for the direction on this issue, is there a way to make this
connection sessionless?
Thank you,

The problem is that you have to keep your HTTP session between your GET
requests. So, try something like
wget --save-cookies cookies.txt --load-cookies cookies.txt
--keep-session-cookies http://localhost:8161/demo/message/TEST1?type=queue
if you're playing with wget, or something similar in your scripting code
(or just use Stomp ;))
Cheers
