Proxy server errors - Apache 1.39 on OpenBSD 4.2

Cara Tock — Tue, 09 Sep 2008 21:48:07 GMT

I am running proxy servers with the following Apache, mod_ssl and OpenSSL:

Server: Apache/1.3.29, Interface: mod_ssl/2.8.16, Library: OpenSSL/0.9.7j

I am taking intermittent errors in the /var/www/logs/access_log and error_log files.

End-users are occasionally taking Proxy Server” errors (not getting enough info from end-users. Am trying, though)

Please see /var/www/logs/error_log excerpt below.

I have also included an excerpt of /var/www/conf/httpd.conf file (see bottom of email)

Any suggestions on why the mod_ssl: SSL handshare interrupted by system keep occurring – other than pressing “stop” in the browser. We are trying to narrow the issue down and appreciate the help with this:

PLEASE NOTE: Have the following HTTP response directives in place

Specifically, added this one to try and make errors above go away…

BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-res
ponse-1.0

# The following directives modify normal HTTP response behavior.
# The first directive disables keepalive for Netscape 2.x and browsers that
# spoof it. There are known problems with these browser implementations.
# The second directive is for Microsoft Internet Explorer 4.0b2
# which has a broken HTTP/1.1 implementation and does not properly
# support keepalive when it is used on 301 or 302 (redirect) responses.
#
BrowserMatch "Mozilla/2" nokeepalive
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-res
ponse-1.0
#BrowserMatch "MSIE 4\.0b2;" nokeepalive downgrade-1.0 force-response-1.0
#
# The following directive disables HTTP/1.1 responses to browsers which
# are in violation of the HTTP/1.0 spec by not being able to grok a
# basic 1.1 response.
#
BrowserMatch "RealPlayer 4\.0" force-response-1.0
BrowserMatch "Java/1\.0" force-response-1.0
BrowserMatch "JDK/1\.0" force-response-1.0

The WebApp is running on IIS.

Thank you in advance for any assistance or guidance that you can provide with this. Thank you.
