1.4.1. RHBA-2010:0700: bug fix update
apr-util is a utility library used with the Apache Portable Runtime (APR). It aims to provide a free library of C data structures and routines. This library contains additional utility interfaces for APR; including support for XML, LDAP, database interfaces, URI parsing, and more.
* The "resource list" (reslist) interface did not respect the time-to-live parameter. Use of this interface by Apache httpd's mod_proxy resulted in connections which could outlive the configured "ttl" attribute. With this update, inactive connections do not outlive the configured "ttl" with mod_proxy. ( BZ#632096
All users of apr-util are advised to upgrade to these updated packages, which resolve this issue.
