Disabling browser cache

[Rustem]

My setup:

• Firefox on Windows desktop
• Node.js
• Content wikis “work” and “home”, each includes a “base” edition wiki which contains all my customizations.
• I don’t serve the base edition separately. When I need to modify any customizations, I just do it from “work” or “home”, and then restart the other one so it picks up the changes.

I was noticing that even after a restart of tiddlywiki and a page refresh in the browser, I would still see a previous version of a tiddler that I edited in the other wiki. A second page refresh would then bring up the updated version.

Here’s a tiddler I created to disable caching and it seems to have helped:

tags: $:/tags/RawMarkup
title: HTTPHeaders
type: text/vnd.tiddlywiki

<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="cache-control" content="no-store" />
<meta http-equiv="pragma" content="no-cache" />
<meta http-equiv="expires" content="0" />

Hi Rustem

Interesting, I've not encountered this before. It may be worth making a github ticket for a more flexible solution: to modify server.js to enable cache headers to be explicitly specified in tiddlywiki.info.

Best wishes

Jeremy.
