Last Saturday shortly before midnight I was listening to the radio, my ear-buds plugged in tightly and slowly falling asleep only for this tune to awaken my auditive senses, urging me to wake up and really listen;
Update 2016: since AO 2.0, inline JS is not aggregated by default any more, which should prevent cache-size problems from occurring. Easiest solution for cache size issues is to make sure “aggregate inline JS” (and CSS) option is disabled. Below HowTo remains relevant in case you decide to enable the aggregation of inline code.
Confession time: Autoptimize does not have its proper cache purging mechanism. There are some good reasons for that (see below) but in most cases this is not something to worry about.
Open two similar pages (posts).
Copy the source of each to a seperate file and replace all semi-colons (“;”) with semi-colon+linefeed (“;\n”) in both files.
Execute an automatic comparison between the two using e.g. diff (or “compare” in Notepad++), this should give you one or more lines that will probably be almost the same, but not exactly (e.g. with a different nonce or a postid in them).
Go to the autoptimize settings page and make sure the advanced settings are shown.
Now add the strings or filenames from (6) to “Exclude scripts from Autoptimize:” (which is a comma-seperated list).
Re-enable JS optimization.
Save settings & clear cache.
This does require some digging, but the advantages are clear; a (much) smaller cache-size on disk and better performance for your visitors. Everyone will be so happy, people will want to hug you and there will be much rejoicing, generally.
So why doesn’t Autoptimize have automatic cache pruning? Well, the problem is a page caching layer (which could be a browser, a caching reverse proxy or a wordpress page caching plugin) contains pages that refer to the aggregated JS/CSS-files. If those optimized files were to be automatically removed while the page would remain in the page caching layer, people would get the cached page without any JS- or CSS-files being available. And as I don’t want Autoptimize to break your pages, I didn’t include a automatic cache purging mechanism. But if you have a bright idea of how this problem could be tackled, I’d be happy to reconsider, off course!
I just “discovered” Child of Lov (a.k.a. Martijn Teerlinck, a young man who was born in Belgium/ Flanders but was raised in the Netherlands) and then learned the guy had died after heart surgery 2 months ago. Damn!
Damon Albarn (you know, the guy behind Blur & Gorillaz) is about to release a solo album later this year. “Everyday Robots” is the first track released. I really love the downbeat feel of the song & and how almost every instrument has a “percussive role”.
