Cookies with multithreaded connection manager - [was Re: Any
equivalent to setReuseAddress() to true - ie reuse sockets in TIME_WAIT
state]
Hi,
Thanks for the tip. I have tried this, but ran into a problem with cookies
when using it.
I created a single HttpClient instance, with a
MultiThreadedHttpConnectionManager. I pass this client to each thread that
I start.
However, I also need to keep track of session information for each thread,
and am not sure how to do that in this model (I get another connection from
my caller, and hence another thread spawned, which must be part of the same
session). I was just calling setState as follows if the thread was part of
a particular session like this:
if (_session != null)
{
// adding session cookie previously saved");
HttpState initialState = new HttpState();
initialState.addCookie(_session);
_httpClient.setState(initialState);
}
This obviously doesn't work with multiple threads accessing the same
HttpClient.
What am I missing? Is there another way to do cookies?
thanks,
David

David,
What kind of connection manager are you using? If yes, consider using
the so called multithreaded connection manager that maintains a pool of
connections:
http://jakarta.apache.org/commons/httpclient/3.0/threading.html
Hope this helps,
Oleg

David,
Create a instance of HttpState per thread and pass it to
HttpClient#executeMethod as a parameter. This should do the trick
