+ *
+ * Revision 1.145 2008/10/09 18:21:41 fabiankeil

+ * Treat unknown change-x-forwarded-for parameters as fatal errors.

+ * If change-x-forwarded-for{add} is used and the client
+ * sends multiple X-Forwarded-For headers, append the client's

+ * Remove hide-forwarded-for-headers action which has

+ * Revision 1.141 2008/09/19 15:26:28 fabiankeil
+ * Add change-x-forwarded-for{} action to block or add
+ * X-Forwarded-For headers. Mostly based on code removed
+ * before 3.0.7.

+ * s@Insufficent@Insufficient@
+ *
+ * Revision 1.135 2008/05/21 20:12:10 fabiankeil
+ * The whole point of strclean() is to modify the
+ * first parameter, so don't mark it immutable,
+ * even though the compiler lets us get away with it.
+ *
+ * Revision 1.134 2008/05/21 19:27:25 fabiankeil
+ * As the wafer actions are gone, we can stop including encode.h.
+ *
+ * Revision 1.133 2008/05/21 15:50:47 fabiankeil

+ * Streamline sed()'s prototype and declare
+ * the header parse and add structures static.
+ *
+ * Revision 1.131 2008/05/20 20:13:30 fabiankeil

+ * first_run hack and make server_patterns_light static.
+ *
+ * Revision 1.130 2008/05/19 17:18:04 fabiankeil
+ * Wrap memmove() calls in string_move()
+ * to document the purpose in one place.
+ *
+ * Revision 1.129 2008/05/17 14:02:07 fabiankeil
+ * Normalize linear header white space.
+ *
+ * Revision 1.128 2008/05/16 16:39:03 fabiankeil
+ * If a header is split across multiple lines,
+ * merge them to a single line before parsing them.
+ *
+ * Revision 1.127 2008/05/10 13:23:38 fabiankeil
+ * Don't provide get_header() with the whole client state
+ * structure when it only needs access to csp->iob.
+ *
+ * Revision 1.126 2008/05/03 16:40:45 fabiankeil
+ * Change content_filters_enabled()'s parameter from
+ * csp->action to action so it can be also used in the
+ * CGI code. Don't bother checking if there are filters
+ * loaded, as that's somewhat besides the point.
+ *
+ * Revision 1.125 2008/04/17 14:40:49 fabiankeil
+ * Provide get_http_time() with the buffer size so it doesn't
+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.124 2008/04/16 16:38:21 fabiankeil
+ * Don't pass the whole csp structure to flush_socket()
+ * when it only needs a file descriptor and a buffer.

+ *
+ * Revision 1.121 2008/01/05 21:37:03 fabiankeil
+ * Let client_range() also handle Request-Range headers
+ * which apparently are still supported by many servers.
+ *
+ * Revision 1.120 2008/01/04 17:43:45 fabiankeil
+ * Improve the warning messages that get logged if the action files
+ * "enable" filters but no filters of that type have been loaded.
+ *
+ * Revision 1.119 2007/12/28 18:32:51 fabiankeil
+ * In server_content_type():
+ * - Don't require leading white space when detecting image content types.
+ * - Change '... not replaced ...' message to sound less crazy if the text
+ * type actually is 'text/plain'.
+ * - Mark the 'text/plain == binary data' assumption for removal.
+ * - Remove a bunch of trailing white space.
+ *
+ * Revision 1.118 2007/12/28 16:56:35 fabiankeil

+ * time, mutated into a "guaranteed to happen" block.
+ *
+ * Revision 1.114 2007/10/19 16:56:26 fabiankeil
+ * - Downgrade "Buffer limit reached" message to LOG_LEVEL_INFO.
+ * - Use shiny new content_filters_enabled() in client_range().
+ *
+ * Revision 1.113 2007/10/10 17:29:57 fabiankeil
+ * I forgot about Poland.
+ *
+ * Revision 1.112 2007/10/09 16:38:40 fabiankeil
