+ * Revision 1.66 2006/09/03 19:38:28 fabiankeil
+ * Use gmtime_r if available, fallback to gmtime with mutex
+ * protection for MacOSX and use vanilla gmtime for the rest.
+ *
+ * Revision 1.65 2006/08/22 10:55:56 fabiankeil
+ * Changed client_referrer to use the right type (size_t) for
+ * hostlenght and to shorten the temporary referrer string with
+ * '\0' instead of adding a useless line break.
+ *
* Revision 1.64 2006/08/17 17:15:10 fabiankeil
* - Back to timegm() using GnuPG's replacement if necessary.
* Using mktime() and localtime() could add a on hour offset if
*
* Description : - Prohibit filtering (CT_TABOO) if transfer coding compresses
* - Raise the CSP_FLAG_CHUNKED flag if coding is "chunked"
- * - Change from "chunked" to "identity" if body was chunked
- * but has been de-chunked for filtering.
+ * - Remove header if body was chunked but has been
+ * de-chunked for filtering.
*
* Parameters :
* 1 : csp = Current client state (buffers, headers, etc...)

/*
- * If the body was modified, it has been
- * de-chunked first, so adjust the header:
+ * If the body was modified, it has been de-chunked first
+ * and the header must be removed.
