The libproxy library provides a stable external API, dynamic adjustment to changing network topology, and small core footprint. It does not use external dependencies within the libproxy core, however libproxy plug-ins may have dependencies. Bug Fix(es) and Enhancement(s): * libproxy: sending more than 102400 bytes in PAC without a Content-Length present could result in buffer overflow [rhel-8.10.0] (JIRA:RHEL-30660)
