Hi

I really need some help. i want to send webpages from my SD card to the browse once the chipkit uno webserver is accessed from a browse.

i saw this code on a site for a arduino uno :

webFile = SD.open("index.htm");        // open web page file
                        if (webFile) {
                            while(webFile.available()) {
                                client.write(webFile.read()); // send web page to client
                            }
                            webFile.close();
                        }

in terms of the chipkit libary how would i send the webpage to the browse/client as they did above "client.write(webFile.read()); "

i tried tcpClient.println that didnt work.

please can someone point me in the right direction, i really need some help

i must also remind u i am still new to the world of arduino.

regards

Del

Here is a snip-it of code that is too be released at some later point. This was tested with a highly modified version of the the sever example that ships with chipKIT Ethernet library (not the DKnet library).
