Added support for multi packets so you can send more than one packet of asked webpage has worked for an 240 mega byte file transfer wihout packet lost speed about 100kbyte / seconds
added new functions (in tcpip.cpp httpServerReply_with_flags() to told the navigator if it is or not the last packet httpServerReplyAck () reply to the navigator an ACK (2. part of three way handshaking)
Exemple number one Send to the navigator a webpage contained in five packets (page a b c d e)
exemple one send a webpage composed of five packets with 900 bytes buffer, you could have 840 * 5 byte page (five packets is only for exemple you can send more packets there is no limitations)
exemple two all the web data are on the SD card tinyfat library don't support folders so all files are in root .hea are headers files if you ask an .htm file , arduino will send htm.hea witch contain HTTP/1.0 200 OK\r\n Content-Type: text/html\r\n Server: Arduino ethercard fred mod\r\n \r\n an then the requested file if you type http://192.168.0.66/test.htm you will see the test.htm page on the root of your SD card the sd library use only 8+3 files don't ark .html files you will become not found.. you can store .js files with correct js.hea change only the mime type (google it to find) you can specify in header files more options Cache (for pictures) so you dont have to reload it every time the default header is txt.hea HTTP/1.0 200 OK\r\n Content-Type: text/plain\r\n Server: Arduino ethercard fred mod\r\n \r\n i have added a server name for exemple but it's not needed
sorry it was code for another test will be come soon : SSDP protocol
reduce ram used it was 80 for SD library while could contain directories but tinyfat doesn't support directories !
i know i must really read my code :-) anothers experiments before brigning this thing working ....

Thanks - committed. I haven't tried this, but am assuming your changes will not affect the existing uses of the EtherCard library too much. |
