annotate proxy_cache_revalidate.t @ 431:05c46688b54b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Tests: ssl_password_file.t fixes. Make sure to always specify listen socket in all servers as the default vary (under root, nginx will try to listen on 80). Make sure to detect if an https request was processed by http.
