I have a third-party WP plugin which, although no longer updated, still works fine - and for which I’ve not been able to find an alternative.
It’s ‘Zajax’ - which ajax-loads internal pages… thus enabling a streaming-radio audio-player to be fixed to the viewport-base, with continuous play throughout page-changes.
However, it appears to require absolute urls - on root-relative urls it reloads the whole page (and thus stops continuous-play).
This is a hindrance, because I normally use root-relative urls - and hence sometimes forget to ensure that all internal urls are absolute rather than root-relative.
I want to modify, so that it’ll work with root-relative urls - but don’t know enough to do this.
It’s time to return to my core skills.
