Hello!
Its a well known fact, that MSIE browsers version 5.x (all platforms) are
having problems with particular SSL ciphers. Especially the 56bit export
versions have a broken SSLv3 implementation. 20.7 percent of our visitors are
using MSIE 5.x. Though more and more users are switching to MSIE 6.x (62.1
%), it is still important to support the buggy browsers.
The default cipher list of OpenSSL [1] looks like this (see
<openssl/ssl.h>):
ALL:!ADH:RC4+RSA:+SSLv2:(at)STRENGTH
The modssl FAQ [2] describes the problem in detail and recommends the
following cipher list:
ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP
This turns off only the 56bit TLS ciphers. If you're running a pounded website
offering SSL encryption, you should add this cipher list at the end of the
"ListenHTTPS" configuration line(s).
