Someone can help me to test this code?
is my project but my ethernet shield not working, i'm waiting for new one.
I need a video of the web server

Hi Tasso,

what do you mean by

I need a video of the web server

do you expect somebody will correct your code setting up everything the PC, the Arduino, a videocamera and the record
how it all works then uploading the video???

First thing, why are there all those [ color=#222222 ] things in the code? Please remove them all.

Second thing, how could anyone test the code when you have not told us what it is intended to do.

Third thing, YOU are person with the code and the hardware so you need to do the testing.

Then if the program does not do what you want you should describe in detail what it actually does and what you want it to do that is different. That way we can focus on the parts you need help with rather than wasting time on things that you can do.

Judging from another topic I read recently the HTML tags are a result of copying the code from the online editor but they are easy enough to get rid of using an editor, even the IDE, but then you might just as well use the IDE to write and test the code in the first place
