[Plugin: WP Super Cache] Cache doesn’t work, plugin = ON and not loggedin WP

    Hi there, i came across a problem with my version 0.9.7 of WP Super cache on WP 2.8.4 and I was wondering if there were more sites with the same problem I found.

    When I’m loggedin into WP with IE or firefox and I choose to set the plugin status to ‘ON’, then the caching works fine when I am using the same browser where I loggedin into WP, and accordingly to the logging it seems to use my cookie, from when I logged in into WP, for temp files.

    BUT, when I logged out of WP in firefox and browse my site in firefox, then the cache for each file is rendered over and over again as I can see in the timestamp. For IE is it the same, after logging out, each page I browse is rendered over and over. And when I take a closer look at the logfile, then I see that there is no line for ‘cookie found’ and it says I am an anonymous user. And I figure that there must be a cookie to use the plugin status ‘ON’?

    So when I use a browser where I’m not loggedin into WP, with the plugin status ‘ON’, then caching does not work properly, because it can’t find the cached file looking for. I could see this very easy because I changed the LOG-line ‘No wp-cache file exists or user agent rejected.’ in “wp-cache-phase1.php” to a more detaild one.

    When I set the plugin status to ‘HALF ON’, then the caching works fine when I’m loggedin into WP or not and it makes no difference if I’m using IE or firefox.
    Could this be a BUG or could it be a configuration failure on my hosting account?

    Also I found a little thing which can be handy:
    1. Choose plugin status ‘ON’ and update status;
    2. Choose Compression ‘Enabled’, so you wil see <!– Compression = gzip –> in the source;
    3. Change the status to ‘HALF ON’ and update status;

    Normaly with status ‘HALF ON’ you can’t see the extra HTML comment for compression, but with step 1 and 2 it will be vissible and can be handy to see and know that compression is used 🙂
    It’s not a bug, It’s a feature 😉

    i hope someone can give a answer to my first caching problem/bug?
