Cache
The SharedSite gateway, on which you made your uploads,
has a cache integrated to the SharedSite's kernel
.
Each time you upload a file, before it is send to your WebServer
, it is copied in the cache.
The size of the cache can vary depending of the disk space we can allow on the SharedSite's gateway.
The advantages of the cache are multiple :
- The last uploads are preserved (also if you update the same file).
This mean it's possible to retrieve
old versions and even to compare them
(more information about the version manager
)
- You can retrieve erased files if they are still in the cache
(E-garbage).
- If the WebServer crashes, we can retrieve the files to send them
(via FTP) on a new WebServer
(the cache must be big enough to keep all the files)
(more
information about the backup option)
Management of the size of the cache
The cache is organised like a FIFO (First In, First
Out).
If the size of the cache is small (for instance some Mo),
it can only keep the few last uploads. Each new file
pushes all the others, and the older uploads
are erased from the cache.
Otherwise, if the size of the cache is bigger than the size
of your website, we'll probably activate the option Active All Site and
doing so, we'll keep :
- the last versions of each published file (a backup ready to use)
- some of the previous versions
We can so do an integral backup of the website.
