+ * ctype.h is needed in Windows, too.
+ *
+ * Revision 1.39 2001/10/26 17:40:04 oes
+ * Introduced get_header_value()
+ * Removed http->user_agent, csp->referrer and csp->accept_types
+ * Removed client_accept()
+ *
+ * Revision 1.38 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.37 2001/10/23 21:36:02 jongfoster
+ * Documenting sed()'s error behaviou (doc change only)
+ *
+ * Revision 1.36 2001/10/13 12:51:51 joergs
+ * Removed client_host, (was only required for the old 2.0.2-11 http://noijb.
+ * force-load), instead crumble Host: and add it (again) in client_host_adder
+ * (in case we get a HTTP/1.0 request without Host: header and forward it to
+ * a HTTP/1.1 server/proxy).
+ *
+ * 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
+ * +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)
+ *

+ *
+ * Revision 1.23 2001/09/12 18:08:19 steudten
+ *
+ * In parse_http_request() header rewriting miss the host value, so
+ * from http://www.mydomain.com the result was just " / " not
+ * http://www.mydomain.com/ in case we forward.
+ *
+ * Revision 1.22 2001/09/10 10:58:53 oes
