* Purpose : Defines data structures which are widely used in the
* project. Does not define any variables or functions
*
* Revisions :
* $Log: project.h,v $
+ * Revision 1.83 2006/12/06 19:26:29 fabiankeil
+ * Moved HTTP snipplets into jcc.c. They aren't
+ * used anywhere else.
+ *
+ * Revision 1.82 2006/09/20 15:50:31 fabiankeil
+ * Doubled size of HOSTENT_BUFFER_SIZE to mask
+ * problems with gethostbyname_r and some
+ * /etc/hosts configurations. Only a workaround
+ * until we get the real fix ready.
+ * Thanks FĂ©lix Rauch for reporting.
+ *
+ * Increased value of MAX_TRUSTED_REFERRERS from 64 to 512.
+ *
+ * Revision 1.81 2006/09/06 13:03:04 fabiankeil
+ * Respond with 400 and a short text message
+ * if the client tries to use Privoxy as FTP proxy.
+ *
+ * Revision 1.80 2006/09/06 10:43:32 fabiankeil
+ * Added config option enable-remote-http-toggle
+ * to specify if Privoxy should recognize special
+ * headers (currently only X-Filter) to change its
+ * behaviour. Disabled by default.
+ *
+ * Revision 1.79 2006/09/06 09:23:37 fabiankeil
+ * Make number of retries in case of forwarded-connect problems
+ * a config file option (forwarded-connect-retries) and use 0 as
+ * default.
+ *
+ * Revision 1.78 2006/08/31 16:25:06 fabiankeil
+ * Work around a buffer overflow that caused Privoxy to
+ * segfault if too many trusted referrers were used. Good
+ * enough for now, but should be replaced with a real
+ * solution after the next release.
+ *
+ * Revision 1.77 2006/08/21 12:50:51 david__schmidt
+ * Formatting cleanup
+ *
+ * Revision 1.76 2006/08/14 08:25:19 fabiankeil
+ * Split filter-headers{} into filter-client-headers{}
+ * and filter-server-headers{}.
+ * Added parse_header_time() to share some code.
+ * Replaced timegm() with mktime().
+ *
+ * Revision 1.75 2006/08/03 02:46:41 david__schmidt
+ * Incorporate Fabian Keil's patch work:\r * http://www.fabiankeil.de/sourcecode/privoxy/
+ *
+ * Revision 1.74 2006/07/18 14:48:47 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
* Revision 1.72.2.7 2006/01/29 23:10:56 david__schmidt
* Multiple filter file support
*
* load balancing. W3C's wwwlib uses 1K, so that should be
* good enough for us, too.
