diff packages/net/athttpd/current/include/http.h @ 2326:bd648d8929f6

* cdl/httpd.cdl: Improve CDL dependencies. * doc/athttpd.sgml: Updated to describe lasted changes and corrected minor typos. * src/http.c: Check for "Content-Type" header. This is needed if we want to support parsing form variables in POST requests. * src/jim.c: Updated with latest release from Jim CVS. * src/cgi.c: streamlined cyg_httpd_exec_cgi_tcl(), now uses the 'source' command of tcl to execute a tcl script. * src/forms.c: Modified cyg_handle_method_POST so that the variables in the payload are scanned only if the request has a Content-Type of 'application/x-www-form-urlencoded' * src/jim-aio.c: Added to package. Now tcl has IO functions to access a file system. * include/httpd.h: Added a new mode, CYG_HTTPD_MODE_FORM_DATA which is set when a POST request has a Content-Type of 'application/x-www-form-urlencoded' * cdl/httpd.cdl: add CYGOPT_NET_ATHTTPD_CLOSE_CHUNKED_CONNECTIONS. Default is set to CLOSE, so it is backward compatible with previous versions of the browser. * src/socket.c: cyg_httpd_process_request() uses a loop to collect at least one full frame (til a header terminator is found), cyg_httpd_start_chunked() only close if configured to do so. * src/httpd.c: Overhaul of cyg_httpd_send_error to avoid the use of inbuffer as temporary storage (conflicts with pipelined frames), removed the option to send a page after calling a C language handler * include/httpd.h: Added a new mode, CYG_HTTPD_MODE_NO_CACHE 2006-10-12 Lars Povlsen <lpovlsen@vitesse.com> and Anthony Tonizzo <atonizzo@gmail.com> * cdl/httpd.cdl: add CYGNUM_ATHTTPD_SERVER_MAX_POST to limit POST'ed data * include/http.h: Added header_end, post_data fields to httpstate, Added "302 Found" for POST handler redirect (CYG_HTTPD_STATUS_MOVED_TEMPORARILY) * src/forms.c: Fixed variable decoding, fixed large POST processing * src/http.c: Fixed some debug ouptuts, cleanup after POST processing, overhaul of the pipelined requests code which can now handle multiple requests per frame. * src/socket.c: Removed assert for socket write failure, Accumulating receiving of requests (Browsers (Firefox) may pass partial headers in separate fragments). Fixed some diagnostics output.
