+ * Revision 1.90 2007/02/08 19:12:35 fabiankeil
+ * Don't run server_content_length() the first time
+ * sed() parses server headers; only adjust the
+ * Content-Length header if the page was modified.
+ *
+ * Revision 1.89 2007/02/07 16:52:11 fabiankeil
+ * Fix log messages regarding the cookie time format
+ * (cookie and request URL were mixed up).
+ *
+ * Revision 1.88 2007/02/07 11:27:12 fabiankeil
+ * - Let decompress_iob()
+ * - not corrupt the content if decompression fails
+ * early. (the first byte(s) were lost).
+ * - use pointer arithmetics with defined outcome for
+ * a change.
+ * - Use a different kludge to remember a failed decompression.
+ *
* Revision 1.87 2007/01/31 16:21:38 fabiankeil
* Search for Max-Forwards headers case-insensitive,
* don't generate the "501 unsupported" message for invalid
