- if 'http_proxy' environment variable is set, respect it when creating http client - otherwise initialize a http client with timeout settings Add ogjson to cache even when it fails in this way we can prevent from requesting unparsable urls repeatedly Extend expire time of cached link preview data to a week There's no need to invalidate cache and send request again frequently Revert timeout Revert cache_expire_time
