I originally asked this question. Regarding a webserver Refresh issue on arduino.

I am totally new to web development and ethernet. The answer from @Majenko is correct, but I do not understand how to implement it. Should I change the homepage() function's first line to HTTP/1.1 307 temporary redirect and use META REFRESH?

Or do the homepage() first using HTTP/1.1 200 OK and then for all the following requests, use HTTP/1.1 307 temporary redirect?
