How do I use an existing HTTP session for install4j?

Question

Using install4j 7.0.2/7.0.3 here.

The main program starts the auto-updater via ApplicationLauncher.launchApplication .

We need to use an existing HTTP (HTTPS actually) session to even access the download site, let alone download stuff.

Is it possible to pass the session ID to the auto-updater so that it will include it in the HTTP headers? Or is there generally a way to pass HTTP header data to the autoinstaller?

Answer 1

The "Check for update" action and the "Download file" action are the ones that make HTTP connections in the update downloader.

Both of them have a "Request headers" property. You can set installer variables for the update downloader with arguments when invoking ApplicationLauncher.launchApplication :

-Vheader1=value1

Then you can use them with the syntax

${installer:value1}

in the request header properties.
