I installed Apache/2.2.22 Ubuntu 12.04. Apache is set as reverse proxy s= erver.

So when accessed from a remote system, the page and conten= ts are

displayed. But after some time the server seems to refuse any further=

requests. The remote browser console gives "net::ERR_CON= NECTION_TIMED_OUT"

error.=C2=A0 But when the ip of the re= mote machine changes (using a dongle which changes ip after
every connect/disconnect), the page/contents displays again.

But the above said issues occur again.

Their is tomcat7 running along with apache. Tomcat is serving the= jsf page through port 8080. All the other requests are handled by apache, = proxy it to

a virtual machine.

In apache2.conf file i mainly changed thes= e directives
=C2=A0
=C2=A0=C2=A0=C2=A0 Timeout 1800
=C2=A0=C2=A0= =C2=A0 KeepAlive On

=C2=A0=C2=A0=C2=A0 KeepAliveTimeout 5
=C2=A0=C2=A0=C2=A0 Include proxy.c= onf

In proxy.conf

also simil= ar VirtualHost directives with port 8082, 8889 with similar settings.

The "cartodb.user" has been = aded in the /etc/hosts file to redirect it to virtual box.

Also the firewall has been disabled for the virtual= box. vVirtual box is also having

Ubuntu 12.04.

In ports.conf

Checked the apache log files didn't give any error when loglevel is p= ut in debug.
