Hi dears.
I am facing a random but very boring proxy error. The environment is the
following:
In the front-end (actually a customer CED):
ProxyPass /webapp
ProxyPass /static
Ap2.0.59<----------------------------->|FW|<---Internet
In the back-end (actually our CED):
ProxyPass /webapp
Internet--->|FW|<--->Ap2.2.8<---------------------------->tomcat 5.5
where Ap is an apache server and FW is a firewall, static is a folder with
static html content and webapp is a servlet running on the final tomcat
instance.
Randomly, when I connect to the front-end apache (2.0.59) and hask for /static
or /webapp, I get a proxy error:
502: proxy: error reading status line from remote server **.**.**.**,
referer:......
This happens both during normal operation and after long idle periods, and
both for static content and for the tomcat webapp. So I think it is a problem
of the two apaches
Now I am suggesting to the front-end system administrator (the 2.0 Apache) to
disable the keepalive with the following setenv directive, something like:
<Location /static>
ProxyPass .....
ProxyPassReverse ....
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
</Location>
<Location /webapp>
ProxyPass .....
ProxyPassReverse ....
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
</Location>
but I have a doubt about tomcat. Should I disable keepalive and HTTP 1.1 on
the tomcat too?
As far as I can understand if I put that setenv directives, everything running
from the client to the tomcat is HTTP 1.0 with no keepalive... I am right?
Is there a way to disable keepalive ONLY between the two apache?
Thank you very much
