           Summary: SSLv3 and keep-alive causes "Page cannot be displayed"
                    in Internet Explorer
           Product: Apache httpd-2.0
           Version: 2.0.53
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_ssl
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: eirik.gjesteland@accenture.com


Internet Explorer opens up to four http connections to the web server 
(configured as reverse proxy). These are in ESTABLISHED state for the duration 
of the keep-alive timeout period. Then they enter CLOSE_WAIT state, where they 
stay for a few seconds. If the user tries to go to a new page AND "friendly 
http error messages" is enabled in Internet Explorer, the infamous "The page 
cannot be displayed" appears.

This has been reproduced with httpd 2.0.52 and 2.0.53 with OpenSSL 0.9.7b, 
0.9.7d and 0.9.7g. We were not able to reproduce the bug in 2.0.40 or 2.0.47 
(all config files were equal), which makes us believe some sort of bug or 
incampability with Explorer is introduced some time after 2.0.47. One will have 
to go via a proxy in order to reproduce it.

For performance reasons, it is not an option to disable keep-alive.

Disabling SSLv3 "fixes" the problem.
