Changelog
+Daniel Fandrich (7 Oct 2008)
+- Changed the handling of read/write errors in Curl_perform() to allow a
+ a fresh connection to be made in such cases and the request retransmitted.
+ This should fix test case 160. Added test case 1079 in an attempt to
+ test a similar connection dropping scenario, but as a race condition, it's
+ hard to test reliably.
+
Daniel Stenberg (7 Oct 2008)
- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then
the app re-used the handle to do a connection to host B and then again
