+ * Fix a cparser warning.
+ *
+ * Revision 1.125 2008/11/20 08:22:28 fabiankeil

+ *
+ * Revision 1.121 2008/10/09 18:21:41 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.

+ * Move parsers structure definition from project.h to parsers.h.
+ *
+ * Revision 1.115 2008/05/19 16:57:20 fabiankeil
+ * Declare all members of the parsers structure immutable.
+ *
+ * Revision 1.114 2008/04/11 16:35:39 fabiankeil
+ * Oops, I forgot to shorten the URL_SPEC_INITIALIZER in my last commit.
+ *
+ * Revision 1.113 2008/04/10 14:41:04 fabiankeil
+ * Ditch url_spec's path member now that it's no longer used.
+ *
+ * Revision 1.112 2008/04/06 15:18:34 fabiankeil
+ * Oh well, rename the --enable-pcre-host-patterns option to
+ * --enable-extended-host-patterns as it's not really PCRE syntax.
+ *
+ * Revision 1.111 2008/04/06 14:54:26 fabiankeil
+ * Use PCRE syntax in host patterns when configured
+ * with --enable-pcre-host-patterns.
+ *
* Revision 1.110 2008/03/29 12:13:46 fabiankeil
* Remove send-wafer and send-vanilla-wafer actions.
