From f933449d3b6c24e66d4a0c590bca3e7b2a39140d Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 6 Aug 2019 11:30:08 +0200 Subject: CURLINFO_RETRY_AFTER: parse the Retry-After header value This is only the libcurl part that provides the information. There's no user of the parsed value. This change includes three new tests for the parser.
