DF 2.4.1 Add extra information upon open registration

You are able to to change headers and parameters in calls made within a script. There was some buggy behavior around this previously, but changing headers has been supported for a while, and changing parameters via the platform object (rather than manually changing them in the request url) was added in 2.4
See the scripting documentation: Scripting: The Platform Resource for details.
Additionally, you can see this blog/script I wrote that actually uses these items here: Database Table Endpoint Obfuscation Through Custom Scripting
