https://docs.goshs.de/usage/templating/index.html goshs can render placeholders inside served text files at download time, so you host a payload once and let goshs fill in your callback host and port instead of editing and re-uploading the file every time your interface or listener changes. Templating is opt-in twice: it must be enabled with --template, and it only runs for a request that explicitly asks for it with the ?tpl query parameter. Every other request serves the file verbatim.
