best magento htaccess for performance

magento.stackexchange https://magento.stackexchange.com/questions/4978

Question

we have installed several extensions and bits and pieces of code to optimize Magento htaccess. Now I see the code has gotte quite long and I am not sure this is all conflicting or supporting ...

So this is what we have so far. What are the best settings?

############################################
## http://www.magentocommerce.com/wiki/groups/227/allowed_memory_size_exhausted  
## Increase memory limit according to Magento
php_value memory_limit 64M
php_value max_execution_time 18000

############################################
## enable resulting html compression of php output
php_flag zlib.output_compression on

############################################
## enable apache served files compression (not php, html/images/css/js
## http://developer.yahoo.com/performance/rules.html#gzip

<IfModule mod_deflate.c>
# Insert filter on all content
SetOutputFilter DEFLATE
# Insert filter on selected content types only
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript
# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# Don't compress images
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
</IfModule>

############################################
## Enable keep-alives to reduce # http requests
## http://yoast.com/magento-performance-hosting/

<ifModule mod_headers.c>
    Header set Connection keep-alive
</ifModule>

############################################
## Add default Expires header
## http://developer.yahoo.com/performance/rules.html#expires

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 14 days"
</IfModule>

and as I understand the next improvement is moving all these rules in htaccess to the virtualhost configuration directives mentioned here:

Was it helpful?

Solution

You could increase the memory_limit to the minimum recommended 256MB. Outside of that, there's no real performance improvement to be gained in editing your htaccess.

The best htaccess is not having one at all. Move and/or rewrite your rules into your vhost definition in Apache and disable overrides.

For highest performance use AllowOverride None everywhere in your filesystem.

OTHER TIPS

By default, Magento comes with a .htaccess file that you can use for your installation. However, this .htaccess file is not optimized and misses a lot of things that can help your site. Therefor, we have created a .htaccess file for Magento that focusses on site speed, security and SEO. You can copy and paste it to use it as your own .htaccess file on your server.

The best .htaccess is no .htaccess. That means migrating all the .htaccess rules into your Apache (or other flavour of Web server) configuration.

One really good way to do this is to search for all .htaccess files in the Magento root and subfolders, combine these into one correctly formatted file and include this in your Apache config :

# Include combined Magento .htaccess files
<Directory /your_magento_root_here>
  AllowOverride None
</Directory>
Include /your_magento_root_here/.htaccess-combined

More information as to how to achieve this and a script you can use to create the combined .htaccess can be found here:

http://colin.mollenhour.com/2010/06/30/the-right-way-to-optimize-apaches-htaccess-files/

Whenever you upgrade Magento, run the script again and restart your web server to pick up any changes in .htaccess rules.

Here is my blog in .htaccess file in Magento.

Hope this will help.
