Connection pool timeout
Hi :)
Is there a way to specify a TIMEOUT value for connections to other hosts and
another TIMEOUT for waiting a free connection from the pool?
I found in previous versions ConnManagerPNames.TIMEOUT and
CoreConnectionPNames.
CONNECTION_TIMEOUT but now theres only
CoreConnectionPNames.CONNECTION_TIMEOUT.
Thanks in advance.

You can now set a timeout for connection manager operations with
ConnManagerParams#setTimeout() when using the latest snapshot off the
4.1.x branch or
HttpClientParams#setConnectionManagerTimeout() when using the latest
snapshot off the trunk (4.2)

Hi Oleg,
It would be great to have another parameter. This is really useful for me,
I'm sorry if my english is not as good as it should be
in order to explain it better.
I need to load a lot of url's. I need to load them whenever connections from
pool are available, it doesnt matter if its now or in 10 minutes. -->
TIMEOUT value infinite
I dont want to block a connection more than 10 seconds waiting for a
response from server. TIMEOUT value 10 seconds
Thanks again Oleg,
Jordi

I am not sure I fully understand why this is useful, but I can
re-introduce a separate parameter for connection manager timeout, if
necessary.

Im using a ThreadSafeClientConnManager with a max total of 50. If all of
them are busy,
waiting resources will timeout and I dont want this.
On the other side, if a timeout waiting for a connection to be established
occurs, I will
retry twice and then assume site is down.
I dont care if a connection is served from the pool or is new.
Thanks,
Jordi

But why? Why do you care if a connection has been served from the pool
or newly created? In both cases one simply needs to ensure that I/O
threads do not get blocked indefinitely while waiting for a connection
to be established.

Hi Oleg,
I need an infinite timeout waiting for a connection from the pool ( i need
the resource to load, whenever possible, doesnt matter if its now or in 5
min).
I need a low value timeout when connecting to a host.
Now when a connection pool timeout occurs I queue it again but i'm not happy
with this.
I think that increasing the pool size will not be good for my BW.
Thanks,
Jordi

Not any more. What are the reasons you would like to use different
timeout values for these two operations?
