Stop caching pdf

[NikosCodeA]

Hello!
I have made a small sevrver using livereload (python) inside wsl (on windows). I have downloaded and store the pdf.js locally and works fine. I use lualatex to generate a pdf
automatically. Every time i make a change in the tex file the pdf is generated causing page to relload, but as far as i understand the pdf is cached so it keeps showing an old version of it except if i manually change the name of the file. I would like to know how to stop PDF.js from caching the pdf so that always the newest version is being displayed...
