For example, I make a LED blinking with wifiserver but I want to turn it off, but when the loop starts, page is disable, how can I run these infinite loops in the background but accept another request?

What you need to do is keep checking for clients/requests every so often and control the LED, sort of multitasking. You can do this by using a counter, or the system clock, in brief what you would do is:-

Loop Start
Check for HTTP requests, process as required
If LED should be flashing AND <0.5s has elapsed, turn LED off
If LED should be flashing AND <1s has elapsed, turn LED on
Loop end
