    Hi, Jacques,

    The mod_ssl how-to explains how to run an SSLv2-only Apache server, but not
    SSLv2, but assuming that the httpd.conf syntax is the same I thought I'd
    substitute the two lines

            SSLProtocol -all +SSLv3
            SSLCipherSuite SSLv3:+HIGH:+MEDIUM:+LOW:+EXP

    for the line

    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL

    in that file. Any idea whether this is correct?

    Thx. Hope you're well!

    David
