PaulS:
You need to show ALL of your code. That snippet makes it look like the Arduino is a client. Clients make GET requests. Servers do not. Your question is about serving up a login page.
Are you implementing a server, that needs to provide data only to authorized clients, or are you implementing a client that needs to log on to a server?
I am implementing a WebServer , and i need an Authorization for the clients that connects to it. I dont want form authentication , i need the basic authentication.
i will also save the username and password to EEPROM and client will change it from the webserver UI.
But i do not know if this can be implemented into Mega2560 with Ethernet shield (i am at work can't test this)

I finally found the solution , i can use http basic authentication with the classic ethernet library with the help of webduinos library,
this is for somebody searching the same , and if you have some better solution or comments i will be glad to hear them

I'm using a code in the STARWEB function that refresh each 5 seconds, but all time that the page refresh appers the hello message in a black page some body solved this issue?
