Updating appfabric cache when file changes

Question

Hi,

I'm using appfabric cache like this -

DataCache dataCache = dataCacheFactory.GetDefaultCache();
if (dataCache.Get("myCacheData") == null)
            {
                string path = MapPath("App_Data/CacheData.txt");

                // Open the file to read from.
                readText = File.ReadAllLines(path);
                dataCache.Put("myCacheData", readText);
            }
            else
            {
                readText = (string[])dataCache.Get("myCacheData");
            }

However, how do I ensure that everytime the contents in CacheData.txt changes, the cahce value also gets updated.

Am I using this incorrectly?

Thanks!

Answer 1

Hi,

'CacheData.txt' file contents are specific to your application , right ? When you add item to the cache you can set expiry to a value that you think the contents can get modified. When each time item gets expired you will update the cache with latest file contents. Depending on the period set there might me time period you get stale data. Let me know if this work for you.

Thanks

Thanks for the response.

It would be nice if there was a dynamic mechanism whereby if the user changed the data, appfabric would detect the change and self load the new document contents into cache on the fly.

Thanks.
