* Revisions :
* $Log: project.h,v $
+ * Revision 1.94 2007/04/15 16:39:21 fabiankeil
+ * Introduce tags as alternative way to specify which
+ * actions apply to a request. At the moment tags can be
+ * created based on client and server headers.
+ *
+ * Revision 1.93 2007/03/20 15:16:34 fabiankeil
+ * Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ *
+ * Revision 1.92 2007/03/17 15:20:05 fabiankeil
+ * New config option: enforce-blocks.
+ *
+ * Revision 1.91 2007/03/05 13:28:03 fabiankeil
+ * Add some CSP_FLAGs for the header parsers.
+ *
+ * Revision 1.90 2007/02/07 10:36:16 fabiankeil
+ * Add new http_response member to save
+ * the reason why the response was generated.
+ *
+ * Revision 1.89 2007/01/27 13:09:16 fabiankeil
+ * Add new config option "templdir" to
+ * change the templates directory.
+ *
+ * Revision 1.88 2007/01/25 13:36:59 fabiankeil
+ * Add csp->error_message for failure reasons
+ * that should be embedded into the CGI pages.
+ *
* Revision 1.87 2007/01/01 19:36:37 fabiankeil
* Integrate a modified version of Wil Mahan's
* zlib patch (PR #895531).
