There appears to be a bug with Apache 2.2.13 which I ran into on Windows Server. See the following bug entry: Bug 23403. Opening the error.log for Apache showed the following warning:
warn Init: Session Cache is not configured (hint: SSLSessionCache)
Adding the following lines to the httpd.conf fixed the problem:
SSLSessionCache "shmcb:c:/Apache/logs/ssl_scache(512000)" SSLSessionCacheTimeout 300
Note: your Apache installation directory is probably different, so you will want to modify the above file path.
