Subject Re: [users@httpd] ProxyTimeout and mod_rewrite proxy request
Date Wed, 30 Jan 2008 19:29:33 GMT
Hi Christian!

Thanks for your answer.

My config is rather simple, everything is set by default.

Here is also:
# grep -ri timeout /etc/apache_aux2/ | grep -v original

/etc/apache_aux2/extra/httpd-default.conf:# Timeout: The number of
seconds before receives and sends time out.
/etc/apache_aux2/extra/httpd-default.conf:Timeout 300
/etc/apache_aux2/extra/httpd-default.conf:# KeepAliveTimeout: Number of
seconds to wait for the next request from the
/etc/apache_aux2/extra/httpd-default.conf:KeepAliveTimeout 5
/etc/apache_aux2/extra/httpd-ssl.conf:#   to use and second the expiring
timeout (in seconds).
/etc/apache_aux2/extra/httpd-ssl.conf:SSLSessionCacheTimeout  300
/etc/apache_aux2/extra/httpd-mpm.conf:#    IdleTimeout           60
/etc/apache_aux2/extra/httpd-mpm.conf:#    ExpireTimeout        300
/etc/apache_aux2/httpd.conf:ProxyTimeout 300

# grep httpd-default.conf /etc/apache_aux2/httpd.conf
Include /etc/apache_aux2/extra/httpd-default.conf

May be you have some more ideas? Thnx in advance.
