defaulthttpclient - connected ?
Hi all,
Is there a way to check that I'm still connected w/ defaulthttpclient ?
Essentially,
I'm logged into a server and if the login session gets timed out or not,
I just quickly
want to check, but I don't see any easy methods to utilize ...
Thanks,
Jim

HTTP session and HTTP connection are two completely different things.
HTTP session may well span across multiple HTTP connections. If a
connection gets closed it does not mean the session get automatically
invalidated.

No, I'm saying that this login/logout stuff is all server dependent.
What you need to do depends on the server and its session management,
which has nothing to do with HttpClient.
For example, maybe you need to just go a GET to a URL every hour, and
that activity is sufficient for the server to keep your session active.
There's also the issue of state stored in cookies, but again whether
or not that's important depends on the server's session management
implementation.

RE: defaulthttpclient - connected ?

I'm trying not to continually login/out, what I want to do is
hold the session open, but if I'm not active, I will get logged
out. If I am, I can start the login session again, but I want
to check ahead to see if I was logged out.
Or, if I open the session, just because I'm not active on the
connection, are you saying that, unlike, coming in through
a browser, the connection will always stay active and I shouldn't
be logged out ? I have not experimented to see if the connection
will always stay open over an long period, say 24 hrs.

This sounds like an issue with the session management of the server,
not HttpClient.
If so, then all you can do is try to ping a URL and check the response
for a 403 (if the server is well behaved). Some servers will just
silently redirect you to a login page, so you'd need to watch for a
temp redirect response.

for a 403 (if the server is well behaved). Some servers will just
