[Plugin: W3 Total Cache] Minify Skip for MSIE User Agents Not Working

    Running WP3.3.1 + 9.2.5a

    I have some issues with the minification and IE. Works great on all other agents.

    I added “MSIE” to my agents to skip in the minify configuration, and MSIE 8.0 without compatible view mode works fine.

    IE 9.0 however does not work in normal or compatible mode.

    I decided to be more specific in user agents and replaced “MSIE” with

    MSIE\ 6\.0
    MSIE\ 7\.0
    MSIE\ 8\.0
    MSIE\ 9\.0

    This just broke the working IE 8.0 scenario.

    I noted that “compatible view” just takes the version back one; i.e. In compatible view, IE8 uses MSIE 7.0, and IE9 uses MSIE 8.0.

    I don’t understand why my first user agent exclusion does not apply to all MSIE agents or why my more specific escaped version does not apply at all.

    In each failed case, I can see the user agent loading the minified js/css in the access logs, and in the working case for MSIE8 it does not.

    Any help appreciated. Right now the site has “MSIE” applied, https://www.netstatz.com

    I still have not found out why the agent filter is not working, however I did solve my problem with IE by using the default HTML minifier rather than HTML Tidy (the only choice on the list).

    I actually thought that Default=HTML Tidy, since no other options are provided; This is the way it works with JS and CSS, except that one of the choice is the default. Being explicit here is misleading, and led me to this problem. I would suggest changing Default to Built-In (default) to reduce errors in minify config, which can be pretty complex anyways.

    Another suggestion is to have the auto JS minification insert itself after CSS fonts. In auto mode, my JS loads before my CSS fonts, with Auto-minify. Gtmetrix degrades me, rightfully so, for not loading all CSS elements before the JS code.

    So now I have full minification working on all agents. W3TC is really powerful = awesome. I’m down to 1s load times, mostly static images.

    This issue is definitely fixed in recent releases.
