Hi Remy

Thanks for your help.

>>AnsiString Buffer = AThread->Connection->ReadLn(LF,IdTimeoutDefault, -1);

Tried this instead of AThread->Connection->ReadLn();
The problem was that later in the program I used AThread->Connection->Write(...) instead of WriteLn(...)

This is just a small piece of testing code - In the actual code, the AThread->Connection is copied to an object and later used to send back the response.

In the actual code I will have better exception handling than ShowMessage :)

>Why not?  Please be more specific.

As I said I have used ReadLn() together with Write(). I have now changed the code as you suggested and it works perfectly.
I had to convert an existing project from TClient and TServer sockets to Indy socket because I needed to use Https components.

I really appreciate your help

Regards
Alfred
