By default, file ending with ".class', ".tml" and ".properties" can be served to the client only if the request includes the file's MD5 checksum. As you would expect, that blacklist can be extended.

This ensures that the hidden binary object data is guaranteed to be unaltered when it returns to the server upon form (or AJAX) submission. The HMAC pass phrase is set using the <a shape="rect" href="configuration.html">tapestry.hmac-passphrase</a> configuration symbol. If you don't set that value, you'll see a warning

Spring Security is the more popular of the two (because of Spring's popularity), whereas Shiro is widely regarded as the more flexible choice. There are well-maintained Tapestry integration projects for both of these frameworks, <strong><a shape="rect" class="external-link" href="http://tynamo.org/tapestry-security+guide" >tapestry-security</a></strong> for Apache Shiro (from Tynamo.org) and <strong><a shape="rect" class="extern
