# Shouts go out to Robe, for - nevertheless! - running that box, and to fin    #
# for making me write this thing [and adding a new feature to net-http-persis- #
# tent and mechanize underway], and to the maintainers of these libraries.     #
# Oh, and <3s to joernchen.                                                    #

Sorry dear, but you're currently running an outdated version of Mechanize o.O
Setting the ssl_version (crucial for Titanpad, which is running on a Jetty 6.1.20) is only possible starting from Mechanize 2.1.2!
See https://github.com/tenderlove/mechanize/commit/4a228899855e0676ab69c2bf548170c8717465d8 as well as the corresponding net-http-persistent update
https://github.com/drbrain/net-http-persistent/commit/5f4a945ccf59538cea63323ccb705ad1a7349477 for more info and delight.

We'll proceed anyways and see how that goes - brace for impact in case I bail out.
