Subject: [PATCH] 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)

  * Revisions   :
  *    $Log: parsers.c,v $
+ *    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
+ *       +no-compression action. For HTTP/1.1 the Accept-Encoding header is
+ *       changed to allow only identity and chunked, and the TE header is
+ *       crunched. For HTTP/1.0, Accept-Encoding is crunched.
+ *
+ *    parse_http_request no longer does anything than parsing. The rewriting
+ *      of http->cmd and version mangling are gone. It now also recognizes
+ *      the put and delete methods and saves the url in http->url. Removed
+ *      unused variable.
+ *
+ *    renamed content_type and content_length to have the server_ prefix
+ *
+ *    server_content_type now only works if csp->content_type != CT_TABOO
+ *
+ *    added server_transfer_encoding, which
+ *      - Sets CT_TABOO to prohibit filtering if encoding compresses
+ *      - Raises the CSP_FLAG_CHUNKED flag if Encoding is "chunked"
+ *      - Change from "chunked" to "identity" if body was chunked
+ *        but has been de-chunked for filtering.
+ *
+ *    added server_content_md5 which crunches any Content-MD5 headers
+ *      if the body was modified.
+ *
+ *    made server_http11 conditional on +downgrade action
+ *
+ *    Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
