HTTPACTION: Small Question

Hi to all
i have setup to send some data that i read with my arduino to my server

at the end i have the command :

AT+HTTPACTION=0

that gives as a result :

+HTTPACTION: 0,200,2

I know that the 0 is for the HTTP Get method and the 200 is the response from my server that is OK

the last number , 2 what is it? is the total amount of data that i send to my server?
is that in bytes ?

thanks in advance
