On our development SP2013 farm, I have enabled Blobcache according to MSDN.
I simply changed the line to enabled=true and create a folder c:\Blobcache.
After some days, I found there is nothing in c:\Blobcache and when I check back web.config, the line of BlobCache have been changed back to default. The Enabled attirube become "False" as default.
What kind of action will cause the change? Do I missed some setup to make attribute fixed? Thanks for advice.
