[Resolved] W3 Total Cache And Page Cache Flush?

  • I have the W3TC Page Cache set to cache the home page and to automatically prime the page cache. I assumed that W3TC would flush the home page cache (and RSS cache) upon publishing of a new post. However, I have found this to be very inconsistent when publishing multiple posts. Sometimes it will flush home page cache completely, while other times not at all, and at other times for one post, but not the others.

    I wonder if I am doing something wrong? Or do not have a proper setting? I would definitely like newly posted articles to go live immediately.

    Thanks!
    Chris

    Are you using the browser cache? Are you logged in when checking this?

    I clear the browser cache before I visit my website as an unlogged user so I can see what a regular user sees. If I view the website logged in then I see the new posts, but not as an unlogged user. This is very inconsistent though. I’ll have to keep investigating. For example, all of my new posts immediately published yesterday, but none posted immediately this morning (I had to clear all caches and then they showed). It could be some weird browser cache problem on my end. I do know. I’ll have to keep testing.

    Again, are you using the browser cache options in W3TC?

    I am using the browser cache options.

    For the last couple of days, this problem has not occurred. The home page cache is flushed for all of my posts. I have no idea why it is now working. So put this issue on hold for now, while I continue to monitor.

    Thanks as always Frederick for taking time to respond.

    Ok, try to review and understand your browser cache settings so you can modify them as needed in the future.

    I thought I did understand them. Perhaps not. I’ll review again. I was under the impression that home page cache would be cleared upon new posts. The thing is, I changed no settings whatsoever when the expected behavior returned. You’d think my initial issue would not have not resolved if I did not change anything… but it did… I’ll keep you posted of the original suspect behavior returns.

    The browser cache is on your local machine, not the server. So if your browser doesn’t think it needs to check for updates it won’t. When the files expire from your browser (and you’re not logged in), things may appear to be fixed, when in fact all that happened was the page expired from the local browser cache.

    Not sure if internet browser cache was the problem… maybe. I’d clear my internet browser cache before viewing my website….Whatever happened, everything works fine now.

    Thanks as always for your replies Frederick.

    Ok, if you have more details on how to duplicate, it would be appreciated.

    Frederick – I ran into some serious issues with my webhost (BlogOnCloud9 -Rackspace cloud webhost) and WT3C. They said they have never seen anything like this. W3TC basically went crazy with consumption of server resources, bandwidth, etc. It got worse and worse over the course of a month. They consulted logs and correlated with the install of W3TC. I installed SuperCache and all resources instantly went back to normal.

    However, I would like to return to W3TC, and the BlogOnCloud9 folks are very interested in your plugin and were watching to see how it worked for my website. They said they would even create a user configuration on their servers for you if you want to a look at what happened. I would also be willing to create temp user for you on my website too if you think this will help figure this out. It is the least I can do to support such a great plugin and your work.

    I do not know your level of interest to sort this out, but if you do, would you prefer to talk back-channel on this?

    Of course I’m interested. It would also be nice to see how you configured things yourself that caused the problem. Once they have things set up, they can submit a bug submission form from the support tab of the plugin to get things started and tracked properly on my end. Thanks for writing.

    Sounds good. I’ll get this rolling this week.

    My first guess, as you suggested, is probably a settings problem on my end. My apologies in advance if I am creating a whole lot of work for everyone. I think the primary suspect will be the disk cache saving (they do not use Memcached on their servers) or possibly the CDN with MaxCDN. I guess we’ll find out.

    Let me know.

    We had to deactivate the plugin for the reason discussed above. I did a quick Google search but couldn’t find your bug forum. Can you provide a link to the bug submission area?
