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
