Hi Jordisan, I'm working on something very similar, and yes, I do use both memcache and the datastore, to ensure that the cached data lasts as long as I want it to. Memcache, IIUC, is not guaranteed to hold onto your data for as long as you specify. So my code looks like this:
on request for data: - Check memcache to see if I have it stored (the identifier is the URL path). This way, oft-requested files are served most quickly. - If not, check the datastore. This way, I don't have to hit the originating site for any non-updated data. - If not, do a URL fetch and grab it, caching it in memcache and datastore. For my purposes, I don't store posts--since they're usually dynamic CGI script requests on the sites I'm using it with, and I don't cache gets that have query strings. Eventually, I'm going to build a management app that will allow me to specify cache time, purge stored data manually, etc., but right now it's set up as described above. -Ben On May 25, 2:49 am, jordisan <ram...@gmail.com> wrote: > Hi. > I'm developing an application which connects to external APIs > (delicious) via URLFETCH.
