On the documentation we have a goof example of an HTTP GET request. What If I have need to de an ECHOREQUEST?

Pray tell what the heck is a ECHOREQUEST? There is no such thing in the HTTP protocol RFCs.

That is ICMP, not HTTP. A completely different thing and three network levels away from HTTP.
As far as I can tell, ESP8266 doesn't support ICMP.

When it has the AT firmware it really does have a "ping command". My question would be, how is it possible then?

Perhaps you can examine the firmware's source and see for yourself. My guess would be that they are doing a so-called "tcp ping".

There are some Arduino Ping libraries for ESP8266, which seem to use ICMP echo requests.
