From 3944ba0cb0ef5119dc9d1708c572855fca88fc43 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Storsj=C3=B6?= Date: Wed, 1 Apr 2009 19:48:24 +0300 Subject: Allow curl to rewind the read buffers When using multi-pass authentication methods, the curl library may need to rewind the read buffers (depending on how much already has been fed to the server) used for providing data to HTTP PUT, POST or PROPFIND, and in order to allow the library to do so, we need to tell it how by providing either an ioctl callback or a seek callback. This patch adds an ioctl callback, which should be usable on older curl versions (since 7.12.3) than the seek callback (introduced in curl 7.18.0). Some HTTP servers (such as Apache) give an 401 error reply immediately after receiving the headers (so no data has been read from the read buffers, and thus no rewinding is needed), but other servers (such as Lighttpd) only replies after the whole request has been sent and all data has been read from the read buffers, making rewinding necessary.
