- * Revision 1.13 1996/01/12 10:05:20 adam
+ * Revision 1.23 1997/01/27 11:27:14 adam
+ * Implemented a new command, egw_clear, to clear http output cache.
+ * Changed prototype for function wo_clear.
+ *
+ * Revision 1.22 1997/01/24 13:13:11 adam
+ * Implemnted egw_source and added a "raw" option to the URL.
+ * Fixed a bug in the buffering system of wproto; the macro wo_putc could
+ * override memory if it was the first HTML generating function called.
+ *
+ * Revision 1.21 1996/05/23 15:53:11 adam
+ * Bug fix: egw_enc failed on 8-bit chars.
+ * New command: egw_parms.
+ *
+ * Revision 1.20 1996/05/21 14:53:04 adam
+ * Tcl command wform extented; options -raw and -exists added.
+ *
+ * Revision 1.19 1996/03/14 11:48:39 adam
+ * New function egw_prog that returns name of shell.
+ *
+ * Revision 1.18 1996/02/12 10:09:23 adam
+ * New parameter to wproto_init: directory root for the FIFOs (instead
+ * of using preprocessor defines FIFODIR/FIFOROOT).
+ *
+ * Revision 1.17 1996/01/26 09:02:22 adam
+ * Open of client FIFO called with O_NDELAY when reconnecting to shell
+ * in order to prevent serious lock if previous shell died without
+ * unlinking client FIFO.
+ *
+ * Revision 1.16 1996/01/24 10:13:56 adam
+ * Bug fix: in function wo_write realloc is used only when memory is already
+ * allocated with malloc.
+ *
+ * Revision 1.15 1996/01/24 08:25:32 adam
+ * Buf fix: Uninitialized outbuffer_offset member.
+ *
+ * Revision 1.14 1996/01/12 13:08:07 adam
+ * CGI script passes name of lock file to the shell. The server will not close
+ * the response FIFO until this file becomes unlocked. This method handles
+ * cancel operations much better.
+ *
+ * Revision 1.13 1996/01/12 10:05:20 adam
* If script name ends with ';' HTTP/GET/Expires will be defined.
* The cgi interface only reads final handshake if response from
* server (shell) was zero-terminated [If it isn't it probably died].
