I experienced some problems with mod_proxy when the backend server is resta=
rted.

This may be due to the reuse of invalid connections=2C hence I tried not to=
reuse them by using disablereuse option:

....
ProxyPass / http://195.238.10.70/ disablereuse=3Don
....

netstat command shows that connections are not reused (one connection per r=
equest) however it seems that the connections are not cleaned up immediatel=
y and stay for a while in TIME_WAIT
I assume we could reach shortly a threshold on the server on TCP connection=
s.

- Is there an option to immediately close the connection without waiting
- When re-using the connections (disablereuse=3Doff)=2C if the backend serv=
er is restarted=2C it seems to hang. Any parameter controlling this behavio=
ur.

Regards=2C
