I don't think that renegotiation is a problem. The problem probably is the ciphersuite selected during renegotiation -- presumably you switch from RC4 to a DES-based cipher. Using RC4 avoids the problem with IE. OpenSSL 0.9.6e or 0.9.7 will allow disabling the empty-fragment method. This is useful when interoperability with MSIE is more important than security. You might want to try the latest beta for OpenSSL 0.9.7. -- Bodo Möller <[EMAIL PROTECTED]> PGP http://www.informatik.tu-darmstadt.de/TI/Mitarbeiter/moeller/0x36d2c658.html * TU Darmstadt, Theoretische Informatik, Alexanderstr. 10, D-64283 Darmstadt * Tel. +49-6151-16-6628, Fax +49-6151-16-6036 ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
