RE: [squid-users] Where are the objects?

Hi,

Squid saves the files to var/cache in subfolders, or any other folder you
configure using cache_dir.

If you shut down squid, delete the FILES in this folder and its subfolder
(do not delete folders, just files), restart squid and access a cacheable
file, you should see a new file added in a sub folder (as well as a swap
file). The new file in one of the sub directories is the cached version of
the resource. You can open it in a text editor. If the original resource was
text (html, css, etc) it will be pretty easy to understand this file.

If you do not see a file on disk, it is possible that the resource is not
cacheable, or the configuration of your squid does not allow disk caching.

Hope this helps,

E

Subject: [squid-users] Where are the objects?

I have a question regarding the storage of objects: Where is really
saved to on disk? Is it in /var/log/squid3/access.log or in:
/var/log/squid3/store.log?

I've noticed that in the /var/log/squid3/cache swaplog there isn't any
entries as stated below. How exactly are objects saved?
