Firefox 3.6.3 Cache Issue


I’ve been customizing Mark Huot’s Livesearch extension for ExpressionEngine, which combines the livesearch jQuery plugin with an ExpressionEngine plugin for returning formatted query results.

The livesearch JavaScript has a built-in caching mechanism that didn’t seem to be clearing in Firefox. In Safari, IE, and others, valid search results (weblog entries) were being returned as one would expect. In Firefox, old/deleted entries were being returned as search results. In Firefox 3.6.3 (both for myself and my client), the browser cache couldn’t be completely cleared.

The only way to fix the problem was to view the JavaScript file (jquery.livesearch.js) directly in the browser, then hold shift and click refresh.

I also updated the headers to prevent excessive caching in the first place.
