Just got my first Arduino today, after an evening's work I am having lots of fun playing with the Ethernet connection. However I have just found out that a service I want to use is only available on https (it's my ISP's usage info). Is https feasible with an Arduino? I suspect not, I might try asking my ISP for a plain old http service (I don't mind a black hat reading my usage information :])
If you have a PC/server at home you might use it as an intermediate. Let the PC fetch the data over https and serve it to the Arduino by means of http.
Good suggestion, since I am making a usage meter there will always be another PC on the network. I could also have a CGI script on the webserver get the information from my ISP.
