[users@httpd] httpd 2.4.2 not closing backend connection after proxypass ttl
expires
Hello,
I am running Apache 2.4.2 as a reverse proxy server. The backend IIS http server has a timeout of 120 seconds for the backend connection. I occasionally see 502 errors because the backend connection is closed by the IIS server and Apache still tries to use it. So I have added "smax=0 ttl=60" to my ProxyPass directive, but apache continues to use this connection after 60 secs of idle time.
I test with making 10 consecutive calls that return good. Apache re-uses the same connection as I would expect. I wait 90 seconds and attempt another connection. It still re-uses the same back-end connection that I would have expected to have timed-out by then. Has anyone else seen this behavior or know of a solution? Any suggestions appreciated.

Sorry that is a typo in the conf file I inherited. It was removed during my testing.

Why double ProxyPass?
ProxyPass / http://localhost-vip.com/smax=0 ttl=60
ProxyPass / http://localhost-vip.com/
ProxyPassReverse / http://localhost-vip.com/
