====== LSCache + Magento ======

**Note: This page describes an easy way to set up simple caching for Magento installations. With the release of [[http://www.litespeedtech.com/products/litemage-cache|LiteMage Cache]], though, this solution is now deprecated. Click [[litespeed_wiki:cache:litemage|here]] for the LiteMage Cache installation and configuration manual.**

===== Summary =====
It is rather simple to have LSCache and Magento work together. LSWS enables private cache and defines URL pattern not to be cached.  

===== Procedures =====
Here are the steps that will enable LSWS to work with Mangento:









==== Set up Cache Policy ====

In LiteSpeed (v4.1.2 or later) Admin CP -> Configuration -> Server -> Cache
<code>
Storage Path: /diskcache
Max Object Size: 128K

Cache Policy
Enable Cache:    No
Cache Expire Time (seconds):    Not Set
Cache Request with Query String:    No
Cache Request with Cookie:    No
Cache Response with Cookie:    No
Ignore Request Cache-Control:    No
Ignore Response Cache-Control:    No
Enable Private Cache:    Yes
Private Cache Expire Time (seconds):    60
</code>
Do-Not-Cache URL(s):
<code>
/checkout/
/admin
/customer
/downloader
</code>
**Note:** 

   - Do-Not-Cache URL box holds all of the URL(s) that should **NOT** be cached.
   - Cache storage can be set to /dev/shm/diskcache to avoid disk I/O wait if enough memory can be spared.
   - Cache resource with size less than 128KB.
   - For cached request, "X-LiteSpeed-Cache: private,hit" response header should be seen. IOW, if no such entry in the response header, the response is not cached by LSWS.



=== Crate a cronjob to clean up stale cache ====

<code>
*/10 * * * * find /diskcache -type f -mmin +10 –delete
</code>

**Note:** This cron job clean up stale cache storage every 10 minutes.


==== Add entries to /etc/rc.local ====
 

     echo "mkdir /diskcache && chmod nobody.lsadm" >> /etc/rc.local
     echo "/diskcache && chmod 770 /diskcache" >> /etc/rc.local
    
**Note:** this is to make sure cache directory gets created when server is booted up.
