How do i test if cache is working

[Ledgemonkey]

what does this mean and how do you use it...?

7. Verify if pages are served from LSWS cache

Since 4.0.19 release, LiteSpeed outputs a response header “X-LiteSpeed-Cache: hit” if a request is served from cache.

Since 4.1.1 release, LiteSpeed outputs a response header “X-LiteSpeed-Cache: hit,private” if a request is served from private cache.

A server response has headers. You can look at via firebug or run command line like 'curl -I http://example.com/path/to/resource'

Connection:Keep-Alive
Content-Encoding:gzip
Content-Length:10108
Content-Type:text/html
Date:Thu, 14 Feb 2013 18:31:00 GMT
Keep-Alive:timeout=5, max=100
Server:LiteSpeed
Vary:Accept-Encoding
X-Litespeed-Cache:hit
X-Powered-By:PHP/5.3.20

A response served from LS cache carries 'X-LiteSpeed-Cache' header as shown above

Thanks for the reply:

I have this in htttp.conf:

LoadModule cache_module modules/mod_cache.so
<IfModule mod_cache.c>
<IfModule mod_disk_cache.c>
CacheRoot /tmp/diskcache/
CacheEnable disk /
</IfModule>
</IfModule>

I have files in tmp/diskcache/ 0/ 1/ 2/ 3/ a/ b/ c/ d/ e/ etc.

my LS cache settings are :

Storage Path:tmp/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): 120

I have this in my Magento .htaccess (which is not in root directory)

RewriteEngine on
RewriteRule cacheable/(.*\.php)?$ - [L,E=cache-control:max-age=120]

Getting this from response header..?

Any ideas where I'm going wrong...?

Many thanks...

I changed the Rewrite to:

RewriteEngine on
RewriteRule (.*\.php)?$ - [L,E=Cache-Control:max-age=120]

And tested using curl -I - X-Litespeed-Cache:hit was in the response , but testing again and has stopped showing up.

Can't be far away...!

Have tried different rules but not working...?

Any ideas...?

Thanks

in cache policy, set ignore request/response cache-control header to yes.

Hi,

Now getting the X-LiteSpeed-Cache: hit response....

Just need to get the rewrite rules correct so I don't cache the admin pages..in magento backend..

[webizen]

you can put the admin page url in the 'Do-Not-Cache URL' box. mouse over the 'i' pop-up window for more information.

Can't seem to exclude the Magento admin area from cache , I've tried various settings in the 'Do-Not-Cache URL' box and in the .htaccess file but cant seem to be able to make it work.

Any idea what the correct code could be in the .htaccess file to exclude all urls which contain "admin"..?

Thanks

[webizen]

you can refer to this wiki for 'Do-Not-Cache URL' settings

[Ledgemonkey]

doesn't work tried all sorts...?

What re-write rules should i use in htaccess ?

If I use this RewriteRule (.*\.php)?$ - [L,E=Cache-Control:max-age=120] my pages break with Use Web Server Rewrites set to "yes" in amgento backend.

Thanks
