+ * Revision 1.68 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 1.67 2006/09/04 11:01:26 fabiankeil
+ * After filtering de-chunked instances, remove
+ * "Transfer-Encoding" header entirely instead of changing
+ * it to "Transfer-Encoding: identity", which is invalid.
+ * Thanks Michael Shields <shields@msrl.com>. Fixes PR 1318658.
+ *
+ * Don't use localtime in parse_header_time. An empty time struct
+ * is good enough, it gets overwritten by strptime anyway.
+ *
+ * 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
*
* 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.
