view proxy_non_idempotent.t @ 1972:f3573393f36f

Tests: guarded ssl_stapling.t for old OpenSSL versions. Stapling requires the certificate status TLS extension. It is implemented in OpenSSL 0.9.8h and available if TLS extensions support is explicitly configured, and by default since 0.9.8j. To properly test if stapling is available, OpenSSL version is checked, and SNI availability is checked to ensure TLS extensions support is compiled in.
