Re: [lwip-users] Dynamic web pages with lwip1.3.2

Thank you very much for your reply. I see what you mean. 
So you recommend me to use ajax/javascript instead of php for the get and
post methods?

Concerning the led, once I parsed the ledstate variable, in my C program I
would just have to put something like:

if(ledstate==on)
{
toggle_led();
}

Is that correct ?

Another thing, if I have a webpage which asks the login and the password, I
understand how to check that login and password are correct but how would
you manage the redirection on the corresponding webpage (and display
dynamically "welcome 'LOGIN'")? 
And at this point, if the C program manages the variables, I don't
understand why and how using the ajax script?
(I'm sorry for all these questions which may seem obvious but I'm a student
and it's quite new for me)
