Hi Jack,

 

>From what I know the cache is cleaned automatically, you have no way to
retrieve something that is cleaned to reset it later.

 

This means you will have to handle this process yourself. I would suggest
storing the result in a separate file so that if your request fails you can
load from the file and store it back in cache. If the requests succeeds you
can store the result in the file and in the cache.

 

Cheers,
Steven

Hi, 
First of all, I don't really know how Zend_Cache works internally, so I'm
making one (possibly incorrect) assumption, that expired items are not
removed from the cache until they are requested via $cache->load();

Now, is the following possible, and if so how?

*       You have a cache set up where stored items expire after 24 hours
*       There is an item in the cache which was added 25 hours ago and
originally came from a remote source
*       You make a request for the item, it has expired, so load() returns
nothing
*       You make a request to the remote system for the latest data
*       If the request is successful the new data is added to the cache in
the usual way
*       If the request is unsuccessful the old data that has now expired is
"reset" to be valid for another 24 hours (or possibly less)

I want to do this in order to ensure that there is never no data available.
Is is possible? Thanks,
