 Also, the ability to set HTTPS\_CA\_FILE and HTTPS\_CA\_DIR might benefit some people. Then again, it I can't see any evidence that the SSL certificate of the server is being checked. See the [[bug_report|ssl_certificates_not_checked_with_openid]] I filed on this separate issue.

+Update 2008-10-26:
+
+Better solution, one that works for both http and https, and uses config options. It appears to work...
+
+Note that using $ua->proxy(['https'], ...); won't work, you get a "Not Implemented" error, see <http://community.activestate.com/forum-topic/lwp-https-requests-proxy>. Also see [[!debbug 129528]].
+
+Also note that the proxy won't work with liblwpx-paranoidagent-perl, I had to remove liblwpx-paranoidagent-perl first.
