The tips for Gzip enabling on sharing hosts installed Unix like OS. I know many resources on Google.com can help you already. So this is not an full guide for enable Gzip. Although I have listed a dozen of tips at the end of this post. Read my story to understand what I wanna share with you. That’s an specific medicine for the guys who is dropping in the same situation I met.

Today, I did the optimization for the blog as usual after the blog(buy STO credit) has been set up. The blog is hosted by Godaddy Sharing Host(Specially, Linux economy plan. Why? As it’s cheap prices and decent CS. If you have any suggestion to me, I appreciate!). After the bog got a nice score with YSlow, I noticed that the title rewrite has been all death. I have used the famous WordPress plugin titled All in One SEO by Michael Torbert. Sincerely, I am so lazy so that I didn’t read the sources code ever. I have to read the code to understand how it works. aha..It uses the function ob_start() to get call callback function in the class to rewrite the original title. That’s where the collision comes from. I have used the ob_start(“gz_handler”) to enable Gzip for buystocredit.com. Read the PHP manual for function ob_end_flush() to know the collision well if you want to know more.
So, the issue I met when I enabled Gzip was clear.

Apache 2.0.x – if the mod_felate enabled by your host provider.

Enable Gzip via Mod_deflate

Apache 1.3.x – if the mod_gzip installed and enabled by your host provider

In order to add the nofollow into the result of wp_get_archives(), you may need a few PHP skills. But it’s simple, means can be understand easily.
The main elements are:

1. Use the echo feature of the built-in function wp_get_archives
2. use the PHP function str_replace to add the nofollow tag into the return built-in function.


<?php
//step1, built-in function usage; pay attention to the echo=0
$month_archives=wp_get_archives('type=monthly&echo=0');
//step2 replace the <a with <a rel="nofollow"
$month_archives=str_replace('>a','>a rel="nofollow"',$month_archives);
echo $month_archives;
?>


As one of the security tips – we should remove the generator information from the header if we are using wordpress for the blog.
It’s simple to do, just remove the following line from the header.php in your theme.

<meta name="generator" content="WordPress <?php bloginfo('version'); ?>" /> <!-- leave this for stats -->
