[solved] getting caching right with enhanced page cache

[nisiwi]

Hello All,

I'm a Litespeed user and have not yet configured Litespeed cache.

For caching currently I'm running wordpress sites with w3 total cache with disk enhanced mode and APC opcode for database and objects.

When disk enhanced mode is enabled additional htacces rules are being applied like so;

# BEGIN W3TC Page Cache cache
FileETag MTime Size
<IfModule mod_mime.c>
AddType text/html .html_gzip
AddEncoding gzip .html_gzip
AddType text/xml .xml_gzip
AddEncoding gzip .xml_gzip
</IfModule>
<IfModule mod_deflate.c>
SetEnvIfNoCase Request_URI \.html_gzip$ no-gzip
SetEnvIfNoCase Request_URI \.xml_gzip$ no-gzip
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/html M7200
</IfModule>
<IfModule mod_headers.c>
Header set X-Powered-By "W3 Total Cache/0.9.2.8"
Header set Vary "Accept-Encoding, Cookie"
Header set Pragma "public"
Header append Cache-Control "public, must-revalidate, proxy-revalidate"
</IfModule>
# END W3TC Page Cache cache

This is causing me some encoding issues as strange characters start to appear within the content, which I suspect is a result of compressing content twice maybe.

I started this thread in releation to the WP extension and then realised that it's probably caused by my environment.

Anyhow, what I would like to understand is what is the most effective configuration for cache that would give me the performance I'm looking for and resolve this problem with encoded characters appearing.

i.e. do I just need to change some htaccess directives and which ones
OR
should I be using Litespeed cache in this setup and how should I configure it

Your advice for a noob on Litespeed would be appreciated.

Oh you can see some examples of the problem on these sites under development.

Thanks,

SetEnvIfNoCase Request_URI \.html_gzip$ no-gzip
SetEnvIfNoCase Request_URI \.xml_gzip$ no-gzip

please try to change to
<IfModule litespeed>
RewriteRule \.html_gzip$ - [E=no-gzip:1,NC]
RewriteRule \.xml_gzip$ - [E=no-gzip:1,NC]
</IfModule>

see if it works.

Thanks Nitewave

Here's what I did.

I just added those to the htaccess file contained in the enhanced disk cache folder for W3TC (didn't remove the mod_deflate.c rules as they don't conflict) and reloaded the page (I didn' rebuild the cache). Output still contains encoded characters.

Any others ideas ?

# BEGIN W3TC Page Cache cache
FileETag MTime Size
<IfModule mod_mime.c>
AddType text/html .html_gzip
AddEncoding gzip .html_gzip
AddType text/xml .xml_gzip
AddEncoding gzip .xml_gzip
</IfModule>
<IfModule mod_deflate.c>
SetEnvIfNoCase Request_URI \.html_gzip$ no-gzip
SetEnvIfNoCase Request_URI \.xml_gzip$ no-gzip
</IfModule>
<IfModule litespeed>
RewriteRule \.html_gzip$ - [E=no-gzip:1,NC]
RewriteRule \.xml_gzip$ - [E=no-gzip:1,NC]
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/html M7200
</IfModule>
<IfModule mod_headers.c>
Header set X-Powered-By "W3 Total Cache/0.9.2.8"
Header set Vary "Accept-Encoding, Cookie"
Header set Pragma "public"
Header append Cache-Control "public, must-revalidate, proxy-revalidate"
</IfModule>
# END W3TC Page Cache cache

I tested the 2 websites you provided in 1st post, they're ok but server is cloudflare-nginx. not sure if litespeed is ok now.

since the 2 sites under development, best to serve directly by litespeed, not behind cloudflare for easier to test.

 

[nisiwi]

cloudflare disabled

Yes both sites run through cloudflare - I've paused cloudflare now so they should go direct.

Both sites display the encoded characters in varying details.

The footer contains (with encoded character)

Forum is replacing character with encoded - Â which is an accented "A"

please try add following to .htaccess
AddDefaultCharset utf-8

it's not likely an issue of

Thank you

of course!

Simple and resolved (that problem) !

OK, now for the rest of the setup. Would you say it could be optimised further and if so what would you recommend ?

Page load times seem to vary from 2 - 6 seconds.

Thanks again NiteWave

Sorry, your question is too general and I'm not able to reply

however the start of the thread is specific and an good question. mark as [solved]

 

[nisiwi]

do I need lite speed

OK, I understand it may not be very specific NiteWave however it is important as I'm wondering why I should be using LiteSpeed at all as I may not be making full use of its capabilities ?

Is there some guidance on optimisation ? i.e. should or could I also be making use of Litespeed cache ?

 

[NiteWave]

I think it depends on your requirement.

can you brief the business plan of your server?
