* Revisions :
* $Log: project.h,v $
+ * Revision 1.127 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 1.126 2008/12/14 17:02:54 fabiankeil
+ * Fix a cparser warning.
+ *
+ * Revision 1.125 2008/11/20 08:22:28 fabiankeil
+ * Remove an obsolete comment.
+ *
+ * Revision 1.124 2008/11/16 12:43:49 fabiankeil
+ * Turn keep-alive support into a runtime feature
+ * that is disabled by setting keep-alive-timeout
+ * to a negative value.
+ *
+ * Revision 1.123 2008/11/10 16:55:59 fabiankeil
+ * Fix a gcc44 warning (in filters.c).
+ *
+ * Revision 1.122 2008/10/16 07:11:34 fabiankeil
+ * Fix a bunch of gcc44 conversion warnings.
+ *
+ * Revision 1.121 2008/10/09 18:21:41 fabiankeil
+ * Flush work-in-progress changes to keep outgoing connections
+ * alive where possible. Incomplete and mostly #ifdef'd out.
+ *
+ * Revision 1.120 2008/09/21 13:36:52 fabiankeil
+ * If change-x-forwarded-for{add} is used and the client
+ * sends multiple X-Forwarded-For headers, append the client's
+ * IP address to each one of them. "Traditionally" we would
+ * lose all but the last one.
+ *
+ * Revision 1.119 2008/09/20 10:04:33 fabiankeil
+ * Remove hide-forwarded-for-headers action which has
+ * been obsoleted by change-x-forwarded-for{block}.
+ *
+ * Revision 1.118 2008/09/19 15:26:29 fabiankeil
+ * Add change-x-forwarded-for{} action to block or add
+ * X-Forwarded-For headers. Mostly based on code removed
+ * before 3.0.7.
+ *
* Revision 1.117 2008/08/30 12:03:07 fabiankeil
* Remove FEATURE_COOKIE_JAR.
