From: Mika Fischer Date: Fri, 04 Nov 2011 14:19:26 GMT Subject: [PATCH v3 2/3] http.c: Use timeout suggested by curl instead of fixed 50ms timeout Message-ID: <1320416367-28843-3-git-send-email-mika.fischer@zoopnet.de> In-Reply-To: <1320416367-28843-1-git-send-email-mika.fischer@zoopnet.de> Recent versions of curl can suggest a period of time the library user should sleep and try again, when curl is blocked on reading or writing (or connecting). Use this timeout instead of always sleeping for 50ms.
