Improve your website performance – 2

Hi friends, in the earlier post I have explained few steps to improve website performance. In this post I am going to explain few more points. Using .htaccess file also we can improve performances of our websites.

We can write below points in our .htaccess file to improve our website performance.

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

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

ExpiresByType text/css "access 1 month”

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


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

<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
