Not possible to set socket lingering on with a socket linger time of 0
----------------------------------------------------------------------
Key: HTTPCLIENT-599
URL: http://issues.apache.org/jira/browse/HTTPCLIENT-599
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 3.0.1
Environment: Windows XP, Sun JVM 1.5.0_07
Reporter: Neil Ferguson
In version 3.0.1 of the Commons HTTP Client it is not possible to set socket
lingering on, but with a socket linger time of 0. This may not appear to make
much sense, but (certainly with the Sun JVM) this is used to force abortive
connection release (see:
http://java.sun.com/j2se/1.5.0/docs/guide/net/articles/connection_release.html).
In the org.apache.commons.httpclient.HttpConnection.open() method the following
code is what prevents this:
if (linger > 0) {
socket.setSoLinger(linger > 0, linger);
}
I have changed this to:
if (linger >= 0) {
socket.setSoLinger(linger >= 0, linger);
}
However this changes the meaning of the http.socket.linger parameter, so this
may not be the preferred solution. Perhaps turning socket lingering on and off
needs to be configured independently of the socket linger time.
