Why multiple uniquely named JS & CSS files in the cache directory?

    Hey Frank,

    Great plugin, but I have some questions for you:

    Why are you creating multiple JS & CSS files in the cache directory?

    I’m trying to use the “CDN” option, but since there are multiple JS & CSS files I’m not sure which one to move up to the CDN for it to point to.

    I notice that it seems different clients get served different names of the same file, but this makes it impossible for me to put my files on the CDN since it will break in some clients – since they seem to potentially get a different filename for the JS / CSS.

    How can I make it work with my CDN with just one file(name)?

    Thanks.

    the file-name is actually determined by the contents of it sh10151. let me explain; AO on the fly combines all JS (or CSS) it finds in a page and for that string of combined code calculates a hash (a fixed length string that is unique and repeatable for the original string). it is the hash that is then used in the filename.

    if you have “also aggregate inline JS” (and to a lesser extent “CSS”) active, it is possible you’re serving different clients differnent AO’d files; some plugins inject inline JS (not in separate files, but in the HTML) that is unique to that page or even for a visitor. if that is the case, you’re going to have to keep an eye on your disk usage.

    regarding CDN; AO works great with a pull cache solution (a CDN that automatically connects to your site to fetch any file it has been asked). If you’re on a push-CDN (as you seem to be), you’ll need something to keep the CDN and autoptimize’s cache folder in sync.

    hope this clarifies,

    Hi Frank, thanks for clarifying.

    I’m using Amazon EC2 as my web server & CloudFront as my CDN. Any suggestions on how to keep a folder in sync?

    don’t know cloudfront myself, but based on this documentation it is “simple” pull-CDN. so assuming your cloudfront URL is sh10151.cloudfront.net, you’d put that in AO’s CDN field?

    Ok, thanks, Frank, I’ll look into that.
    Again, very nice work on the plugin!

    Let me in on this discussion …
    First I want to thank for the plugin, it’s wonderful … thanks.

    I have only a few questions:

    Plugin Area: Cache Information

    Since the default directory of the cache is WP-CONTENT of the site where the plugin is installed … can you change this directory ?? For example, can you save this CACHE in another domain or sub-domain ??

    I await an answer. Thank you in advance! Hugs.
