Improve your website performance

In this post I am going to explain few more points. Using .htaccess file also we can improve performances of our websites.

1. Rewrite urls ( SEO Urls)
2. Expire dates for JS, CSS and Image files
3. Remove ETags for JS, CSS and Image files
4. Compress the files using gzip.

.htaccess file code

#Headers
<ifModule mod_headers.c>
    Header set Connection keep-alive
</ifModule>
<IfModule mod_expires.c>
    ExpiresActive On
    <FilesMatch "\.(ico|jpg|jpeg|png|gif)$">
        ExpiresDefault "access plus 1 month"
    </FilesMatch>
    <FilesMatch "\.(js|css|swf)$">
        ExpiresDefault "access plus 1 month"
    </FilesMatch>
    
# Default directive
ExpiresDefault "access plus 1 month"

# My favicon
ExpiresByType image/x-icon "access plus 1 year”

# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"

# CSS
ExpiresByType text/css "access 1 month”

# Javascript
ExpiresByType application/javascript "access plus 1 year"

</IfModule>

<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)(\.gz)?$">
Header unset ETag
FileETag None
</FilesMatch>


<IfModule mod_deflate.c>

# Insert filter
    SetOutputFilter DEFLATE
# 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

# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following
# workaround to get the desired effect:
    BrowserMatch \bMSI[E] !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>
