Hi,

I'm currently trying to deal with rewrite rules as describe there :http://ez.no/developer/articles/ez_publish_performance_optimization_part_3_of_3_practical_cache_and_template_solutions/static_cache

So, this is what I want to do: The web site have several siteaccess that I want to cache. Let call them "site1" and "site2". The static cache is generated into static/site1 and static/site2.

According to the article, I put this in the .htaccess (I do not have access to httpd.conf):

RewriteEngine On

RewriteCond /home/www/static/site1/index.html -f
RewriteRule ^/$            /static/site1/index.html [L]
RewriteCond /home/www/static/site1/index.html -f
RewriteRule ^$            /static/site1/index.html [L]
 
RewriteCond /home/www/static/site2/index.html -f
RewriteRule ^/$            /static/site2/index.html [L]
RewriteCond /home/www/static/site2/index.html -f
RewriteRule ^$            /static/site2/index.html [L]
  
RewriteCond %{REQUEST_METHOD}     !^POST$
RewriteCond /home/www/static$1/index.html -f
RewriteRule ^(.*)$ /static$1/index.html [L]
 
RewriteRule !\.(gif|css|jpg|png|jar|ico|js)$ /index.php

It doesn't work. When I access to http://mysite.com/index.php/site1, it don't access to the static cache wich is supposed to be http://mysite.com/static/site1/

So, my question is simple : is the code I put in the .htaccess file is good and should work or not?

I am completely lost, if someone can help, it will be really appreciated.

Hi. Anyone have any solutions for this one?

Have you checked what exactly is generated in /static/site1 and static/site2?

the url http://mysite.com/index.php/site1 would translate to:
/home/www/static/index.php/site1/index.html
So first loose the 'index.php'.

I never use static cache for multiple siteaccess in one Ez Publish installation (easier to make multiple installations).
IF it's going to work: you have to have the siteaccess name in your url. ( like http://mysite.com/site1 and http://mysite.com/site2)

According to the instructions :
"You should only add rewrite rules for the VHOSTs for which you want to have static caching. <i>In reality, this means that for each siteaccess that you want to cache, you need a different VHOST block in the Apache configuration.</i>"

I use different rewrite rules (works for 1 siteaccess, could work if you have the siteaccess name in your url, and the /static/site1 and /static/site2 are correctly generated). Example:

RewriteEngine On
# static cache in ez
# no cache for http posts
RewriteCond   %{REQUEST_METHOD} !^POST$
# do not cache vhost admin
RewriteCond   %{HTTP_HOST} !^admin.*$
# non caching vhost for passing the static cache
RewriteCond   %{HTTP_HOST} !^nocache\.mydomain\.nl$
# Does the index.html exist in the static cache?
RewriteCond   /srv/www/dbcc/static$1/index.html -f
#rewrite to the static cache
RewriteRule   ^(.*)$  /static$1/index.html [L]

#default ez rewrites
Rewriterule ^/var/storage/.* - [L]
Rewriterule ^/var/[^/]+/storage/.* - [L]
RewriteRule ^/var/cache/texttoimage/.* - [L]
RewriteRule ^/var/[^/]+/cache/texttoimage/.* - [L]
Rewriterule ^/design/[^/]+/(stylesheets|images|javascript)/.* - [L]
Rewriterule ^/share/icons/.* - [L]
Rewriterule ^/extension/[^/]+/design/[^/]+/(stylesheets|images|javascripts?)/.* - [L]
Rewriterule ^/packages/styles/.+/(stylesheets|images|javascript)/[^/]+/.* - [L]
RewriteRule .* /index.php

If it works, you still have to make a page for 'http://mysite.com/' (or point it to one of the 2 siteaccess). you could use:

# rewrite homepage only
# check for index.html
RewriteCond   $1 =/ [OR]
RewriteCond   $1 =""
RewriteCond   /srv/www/dbcc/static/index.html -f 
RewriteRule   ^(.*)$  /static/index.html [L]
#no index.html
RewriteCond   $1 =/ [OR]
RewriteCond   $1 =""
RewriteRule   ^(.*)$  /index.php [L]

You could make a page for letting the visitor choose the siteaccess and point your homepage there

..
RewriteCond   /srv/www/dbcc/static/site1/choose/index.html -f 
RewriteRule   ^(.*)$  /static/site1/choose/index.html [L]
..
RewriteRule   ^(.*)$  /site1/choose/index.php [L]

I didn't read the complete instructions on http://ez.no/developer/articles/ez_publish_performance_optimization_part_3_of_3_practical_cache_and_template_solutions/static_cache. There are also instructions on using the cache with multiple site-accesses.

But as far as I understand the rewrite rules (http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html) for the given example don't work:

RewriteCond /home/httpd/ez-3.6/static/news_en/index.html -f
RewriteRule ^/$            /static/news_en/index.html [L]
RewriteCond /home/httpd/ez-3.6/static/news_en/index.html -f
RewriteRule ^$             /static/news_en/index.html [L]

RewriteCond /home/httpd/ez-3.6/static/news_fr/index.html -f
RewriteRule ^/$            /static/news_fr/index.html [L]
RewriteCond /home/httpd/ez-3.6/static/news_fr/index.html -f
RewriteRule ^$             /static/news_fr/index.html [L]

If "RewriteCond /home/httpd/ez-3.6/static/news_en/index.html -f" is true, then the root-url ('mydomain.com/) is rewritten to mydomain/static/news_en/index.html and no further rewrites are done. The french siteaccess will only be used if there is no english static cache?!

Hi Stefan, thank you very much for your post.

This is the real urls (for a test siteaccess called "wac_test" right now, but all the other static are already done for en/fr/es/pt/ru) :

the dynamic: http://www.worldaidscampaign.info/index.php/wac_test/
and the static: http://www.worldaidscampaign.info/static/wac_test/

The problem is all the links in the static always referred to the dynamic part, so we need to rewrite every "/index.php/wac_test" with "/static/wac_test" (let's keep the other siteaccess dynamic). I have really no idea how I can do this.
