Switching sockets http request does not work

[Faneduru]

Thanks Tomek!
In this way it works!

I copied the text from the manual. I did not imagine that it is case sensitive. Of course I eliminated all unnecessary extra spaces, but I never thought that the capitals may disturb the result. Especially since it returned the sockets status...
I am afraid that even if it would work sometimes when I should try it in lower case, I could not understand that it is due of that...

Thanks again!
P.S. Such a modification in the pdf manual would be good to be done and appreciated...
