<section name="Introduction">
<p>
Historically there have been security issues associated with TLS
renegotiation. This page describes the renegotiation behaviour of the Tomcat
Native library.
</p>
</section>
<section name="Client initiated renegotiation">
<p>
Client initiated renegotiation is disabled. This behaviour is hard-coded and
cannot be changed.
</p>
</section>
<section name="Unsafe legacy negotiation">
<p>
Support for unsafe legacy negotiation depends on OpenSSL. Unsafe legacy
renegotiation is disabled by default and will not be allowed unless the
OpenSSL configuration option
<code>SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION</code> is set.
