*
* Revisions :
* $Log: parsers.c,v $
+ * Revision 1.35 2001/10/09 22:39:21 jongfoster
+ * assert.h is also required under Win32, so moving out of #ifndef _WIN32
+ * block.
+ *
+ * Revision 1.34 2001/10/07 18:50:55 oes
+ * Added server_content_encoding, renamed server_transfer_encoding
+ *
+ * Revision 1.33 2001/10/07 18:04:49 oes
+ * Changed server_http11 to server_http and its pattern to "HTTP".
+ * Additional functionality: it now saves the HTTP status into
+ * csp->http->status and sets CT_TABOO for Status 206 (partial range)
+ *
* Revision 1.32 2001/10/07 15:43:28 oes
* Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding,
* client_te and client_accept_encoding_adder, triggered by the new
