Subject svn commit: r1148769 - /httpcomponents/httpclient/trunk/httpclient/src/main/java/org/apache/http/impl/conn/tsccm/ConnPoolByRoute.java
Date Wed, 20 Jul 2011 13:45:18 GMT
Author: jonm

New Revision: 1148769

URL: http://svn.apache.org/viewvc?rev=1148769&view=rev
Log:
HTTPCLIENT-1108: backing out my earlier commit of the FIFO structure, to restore
prior functionality. I realized I didn't do this at the right level; we want to
do FIFO at the per-route connection pool level but do LIFO at the "all connections"
level. Will keep working forward on this.
