Magento – best magento htaccess for performance

.htaccessgzipmemoryperformance

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:

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.

Magento 1.7 htaccess Error – How to Fix

After lots of effort i solved the issue. It was an issue caused due to .htaccess

Now after making modifications in .htaccess of the root folder. I checked the subfolders where other two of my websites were kept.

1) First thing i did was delete the .htaccess file in that folders.

2) As my images were not loading, i went to the media folder there i found .htaccess file. The content of .htaccess file was as follows

Options All -Indexes
<IfModule mod_php5.c>
php_flag engine 0
</IfModule>

AddHandler cgi-script .php .pl .py .jsp .asp .htm .shtml .sh .cgi
Options -ExecCGI

<IfModule mod_rewrite.c>

############################################
## enable rewrites

    Options +FollowSymLinks
    RewriteEngine on

############################################
## never rewrite for existing files
    RewriteCond %{REQUEST_FILENAME} !-f

############################################
## rewrite everything else to index.php

    RewriteRule .* ../get.php [L]
</IfModule>

I am not sure how it was giving Internal Server Error. But i deleted it from media folder of both subfolders as i though it wont be much of a risk. This started loading my images.

As i am not an expert on .htaccess i am not sure what security threat it will cause on the website.

It would be great if anyone can advice me on this

Magento – Disable Gzip compression for Magento

Accept Encoding is a request header. This comes from your browser to the server telling the server that this browser will accept the gzip or deflate compression. If the server does compress the resource it will respond with Content-Encoding: gzip.

I am doubtful that you will gain any speed-up with disabling gzip as it is very fast.

However, as this it is hard to tell exactly how to do this since I do not know whether you have only one web server, or a proxy as well which may be introducing compression, and what you actual configuration is...

It looks like you've already done some of this but here's what you should look at:

.htaccess
httpd.conf
Virtual Host configuration file: somewhere in /etc/httpd/conf.d (take a look at httpd.conf for an include statement pointing to the directory where virtual host files may be located)

In general it seems that if you disable mod_deflate in httpd.conf you should be good, as is outlined here: https://scottlinux.com/2012/09/13/disable-http-compression-in-apache/

Debian/Ubuntu:
$ sudo a2dismod deflate
Module deflate disabled. Run '/etc/init.d/apache2 restart' to activate new configuration! $ sudo /etc/init.d/apache2 restart

Red Hat or CentOS: $ sudo nano /etc/httpd/conf/httpd.conf Comment out this line:
LoadModule deflate_module modules/mod_deflate.so
It should now look like this:
#LoadModule deflate_module modules/mod_deflate.so
Close and save the file then restart httpd:
$ sudo /etc/init.d/httpd restart

Hope this helps :)
