Is there an easy way to expire a page and all its children? For example, this page: [http://biola.artofmission.com/news/](http://biola.artofmission.com/news/) and all its children need to be expired whenever a new page is posted in the news section. I was just going to do ResponseCache.instance.expire\_response (page.url) recursively, but I was hoping there was a more elegant way to do it. thanks, ryan ---

Ryan, Unfortunately that’s the only way to do it currently, assuming the structure of your pages requires this. Unless you’re modifying the cache length, the changes will propagate in 5 minutes, of course. Sean ---

I guess also, I’d need to be able to expire a page’s parent, and all the parent’s children. The case where that would be necessary is if the title of the page was changed, so you’d need to regenerate the navigation on all the pages in that section.

I guess at that point it’s almost easier to expire the entire cache! 😉 Sean ---

Sean, > I guess at that point it’s almost easier to expire the entire > cache! 😉 That’s a great point, but the only reason that I don’t want to expire the whole cache is because it takes forever to regenerate each page. I think the slowness is due to the way I have my navigation set up, since it is doing a lot of iteration with if\_children and if\_ancestor\_or\_self to build the navigation and sub-navigation menus. At this point it takes as long as 2 seconds to render a page after the cache is expired. So I guess the issue is not how to creatively expire the cache, but how to speed up the rendering of the navigation. Has anyone done hierarchical navigation like this before? Is there a more efficient way to do it? Thanks!

You can use the dynamic extension: [http://darcs.bigchieflabs.com/radiant/extensions/dynamic/rdoc/](http://darcs.bigchieflabs.com/radiant/extensions/dynamic/rdoc/) You set Dynamic as page type of News…and when you add/remove/update a page under news, the page cache is cleared automatically…is it what you need? * * * Andrea F. removed\_email\_address@domain.invalid [http://bigchieflabs.com/blog/](http://bigchieflabs.com/blog/) [http://think.bigchief.it](http://think.bigchief.it) ---
