Question

ColdFusion Cache object keeps disappearing

Hi,

I recently started using ColdFusion cache (cachePut/cacheGet) in CF10 to store some objects (struct/array).  However, the objects disappear from the cache within a day or so and I have to re-create them.  The cache objects are used regularly so there is no idle time that would cause them to time out.  For good measure, I have also set the "eternal" property of the cache to true. 

Does this have anything to do with the cache limit settings (for component, query caching, etc) in the admin?  I would think not, but I am perplexed as to why my cache keeps getting reset.  Anything I am not doing?

Thank you!

    In the ehcache.xml file you need to change the default cache time.   The file is in the  cfusion/lib directory.  At the end of the xml file in the defaultcache section change the timeToIdleSeconds and timeToLiveSeconds both to "0".  The current setting makes the cache timeout in a day.  Once you change the file restart CF and you should be good to go.  You may need to stop CF to edit the file in some occurances.

    HTH,

    Thanks.  I will give it a try.  I was under the impression that the default timeout in cacheput (according to the documentation) is forever.

    Unfortunately the documentation is wrong.  The ehcache default is to not timeout but it was apparently changed.
