I think You're right as always, that's the first thing I noticed in Mr. 
Aletto working code! IE used 127.0.0.1 with my " header sniffer" server ... 
but I had used http://127.0.0.1:8000/ in its url to make it log with my 
server (working on port 8000) :-)

Yes ... it's a my terrible custom to not check the SendText result ... I use 
to test my projects in my little local LAN, so that function can always send 
all the buffer at once ...

Thank You again! Now I can get rid of the (not working) Indy component in my 
project!
