CMS

Manually clearing your page cache


There are a number of reasons why clearing your page cache can be necessary, mostly during a development cycle where you’re repeatedly publishing out the same pages, or need a site wide change to take place. Normally this isn’t a proble, thanks to the nice “Clear page cache” button.

But sometimes it all becomes horribly stuck, timing out rather than deleting any files. In cases like this you’ll need to manually delete the cache. To do this you’ll need remote desktop access to your CMS server.

Go to your reddot installation folder (in our case D:Reddot)

[installation folder]CMSASPPageCache[Project Guid]

In here you’ll see lots of folders with long, unhelpful names. These are the GUIDs of your projects. To get the correct GUID you will need to go into server manager > Administer Projects and find your project. Once you have clicked onto the project name, select the little i icon at the top of the action menu for the actual project Guid. If you try and find this from within the project itself, you get some other mysterious number; I forget what Reddot said it was now.

You should now have the correct page cache for manual deletion. If you want to be extra careful, it may be worth your while taking a copy of the files just to be safe

Disclaimer

Please be careful! This is your CMS server you’re messing with here… make doublly sure you’re in the right folder before starting to delete files! I’m not responsible if you go deleting your application folders instead of the page cache, sorry.

  1. There are other caches inside the CMS like the ImageCache, the XmlCache and of course the RedDotTemp, maybe an article on these are interesting too. What do you think about it?

  2. Sounds like a plan. Information on what each of these cover would be useful so you know which one to clear if you’re having a specific problem.

  3. We are experiencing real issues with publishing, whereby sites are intermittently loosing their navigation when publishing, even when we clear the navigation cache beforehand. I know that the soap toolkit is not part of the installation, could this be a contributing factor to the poor performance.

  4. Why do you clear the navigation cache? The navigation manager itself is an own .net component of the RedDot CMS. It’s one of the first steps to change the performance influencing components to the faster working .net framework.
    It depends on how you do it, if you clear the navigation cache the index has to be rebuild, if the cache is still clearing in the background and you start the publishing project this could cause the error.

  5. Here’s a question for you. When your navigation is vanishing from the published site does it all vanish, or just parts of it?

    We had an issue where parts of our navigation vanished if a page was in draft. After some investigation we found it was related to our navigation code; navigation manager wasn’t able to see the default value of an option list in a navman template. This issue is fixed in service pack 2.
