Thanks both,

 

Just tested and I confirm that outTerminator = CR LF CR LF works for me.

I think so, see https://stackoverflow.com/questions/5757290/http-header-line-break-style :

 

CR = <US-ASCII CR, carriage return (13)>
LF = <US-ASCII LF, linefeed (10)>
HTTP/1.1 defines the sequence CR LF as the end-of-line marker for all protocol elements except the entity-body

 

And you need two of them at the end of GET:

1. Ends the GET
2. Tells the server that there are no more request headers
