The default cache backend is the files cache in Magento. The default |
|
41
|
|
|
directory of that default cache backend is the directory "var/cache" |
|
42
|
|
|
within the Magento web-root directory (should be blocked from external |
|
43
|
|
|
access). |
|
44
|
|
|
|
|
45
|
|
|
The cache:dir:flish Magerun command will remove all files within that |
|
46
|
|
|
directory. This is currently the most purist form to reset default |
|
47
|
|
|
caching configuration in Magento. |
|
48
|
|
|
|
|
49
|
|
|
Flushing the cache directory can help to re-initialize the whole Magento |
|
50
|
|
|
application after it got stuck in cached configuration like a half-done |
|
51
|
|
|
cache initialization, old config data within the files cache and similar. |
