How can I get the URL of the referring page 
in my cgi-executable:

I have 
void __fastcall TWebModule1::WebModule1Action1(
      TObject *Sender, TWebRequest *Request, TWebResponse *Response,
      bool &Handled)
{

         AnsiString wherefrom = Request->URL;
  
         ... 
}

but wherefrom is empty.

Actually I should have had 
AnsiString wherefrom = Request->Referer;

But this too is an empty string.

Thank you,

Phil

If Indy does not implement that you can query the environment variable
yourself.

What I use in a cgi.exe is:

     if ( getenv ( "HTTP_REFERER" ) )
	printf ( "HTTP_REFERER: %s<br>\n", getenv ( "HTTP_REFERER" )  );

Of course you could sprintf that to a buffer or use AnsiString().printf().

Please report if this does the job.

Hans.

I used:

AnsiString hans = getenv ("HTTP_REFERER");

and it was empty.

I am not using Indy BTW.  Using the example project.  Do you ALWAYS get this with Indy?  Thanks...

I've got the same problem. Referer is always empty, so I can only conclude that it was a 
deliberate omission to stop people writing website tracking programs using BCB.
