Subject: Based on an error report by Philippe Vaucher, we no longer count a retried
X-Git-Tag: upstream/7.37.1~10536
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=32bc30e210ea41552f3dee64edd290a129020dc7;p=platform%2Fupstream%2Fcurl.git

Based on an error report by Philippe Vaucher, we no longer count a retried
connection setup as a follow-redirect. It turns out 1) this fails when a FTP
connection is re-setup and 2) it does make the max-redirs counter behave
wrong. This fix was not verified since the reporter vanished, but I believe
this is the right fix nonetheless.

   PASV even after EPSV returned a positive response code, if libcurl failed to
