Customize User-Agent at Random (Include)

This CustomizeUserAgentRandom-script is a little script done by Thomas Barghahn and modify by Maik Prinz. With this script you are able to change any header and add a trailing text at the end of the Header (IMHO its only reasonable for the User-Agent string). If you found bugs feel free to contact the autor Thomas Barghahn (Th.Barghahn@t-online.de) or Maik Prinz (2prinz@gmx.de).

Example with User-Agent-Header:

"User-Agent: 40tude_Dialog/2.0.15.1de (1643fe98.355.147) (My Newsreader No.1)"

Introduction

For the latest version of CustomizeUserAgentRandom, you need a DLL-file which provides some features like generating the random element of the MID. This DLL-file is available at http://www.nicohaase.de/dExt.dll. This file must be saved in the root of your Dialog-installation.

Install & setup the script

Please note that this script is an include-file!. You have to copy the following script inside a new custom script (for example "Include_CustomizeUserAgentRandom") and safe it. Please don't compile this custom script! After that you have to add the following lines to your OnBeforeSending-Script:

{$I Include_ChangeAnyHeaderRandom.ds}

and

result := result and ChangeAnyHeaderRandom ( Message, IsEmail );

This may look like this:

program OnBeforeSendingMessage;
{$I Include_ChangeAnyHeaderRandom.ds}   

function OnBeforeSendingMessage(var Message: TStringlist; Servername: string; IsEmail: boolean):boolean;
begin
  result:=true;

  //possibly some other calls to scripts

  result := result and ChangeAnyHeaderRandom ( Message, IsEmail );

end;

begin
end.

Just compile this OnBeforeSending-Script now to get your include-file to work. The setup of the script is shown inside the script. Please take a look at this to customize the script to your own fits. Please note that whenever you reconfigure the ChangeAnyHeaderRandom custom script, you have to recompile the OnBeforeSending-Script to apply the changes.

The Include-File

Please be sure that this is the only content in the include-file!
