* Revisions :
* $Log: jcc.c,v $
+ * Revision 1.214 2008/12/20 14:53:55 fabiankeil
+ * Add config option socket-timeout to control the time
+ * Privoxy waits for data to arrive on a socket. Useful
+ * in case of stale ssh tunnels or when fuzz-testing.
+ *
+ * Revision 1.213 2008/12/15 18:45:51 fabiankeil
+ * When logging crunches, log the whole URL, so one can easily
+ * differentiate between vanilla HTTP and CONNECT requests.
+ *
+ * Revision 1.212 2008/12/14 15:46:22 fabiankeil
+ * Give crunched requests their own log level.
+ *
+ * Revision 1.211 2008/12/06 10:05:03 fabiankeil
+ * Downgrade "Received x bytes while expecting y." message to
+ * LOG_LEVEL_CONNECT as it doesn't necessarily indicate an error.
+ *
* Revision 1.210 2008/12/02 22:03:18 fabiankeil
* Don't miscalculate byte_count if we don't get all the
* server headers with one read_socket() call. With keep-alive
