<h3 class="wp-block-heading">Why we need wildcard sub-domain and what is the wildcard sub-domain?</h3>



When you are creating multiple network site or you will allow user to create own site for them on your domain, for this automation process you need Wildcard sub-domain.



When you have fixed number of sub-domain that time you really don’t need to create Wildcard Sub-domain. Wildcard Sub-domain is not related to WordPress only, when you are develop any system base on any&nbsp;platform or framework&nbsp;and you want huge number of sub-domains that time you will use Wildcard Sub-domain.



Wildcard Sub-domain is just like&nbsp;<code>*.yourdomain.com</code>&nbsp;When you will try to access any Sub-domain on&nbsp;<code>yourdomain.com</code>&nbsp;that time you are redirected to your main domain directory or to the Document Root you have choose at the time of creating Wildcard Sub-domain.



<h4 class="wp-block-heading">To create wildcard sub-domain following the steps:</h4>



<ol class="wp-block-list">
<li>Login to your hosting control panel.</li>



<li>Find for Sub-domain under Domains section and click on that.</li>



<li>Enter the <code>*</code> in Subdomain text field.</li>



<li>Choose your domain.</li>



<li>Select your Document Root where you have install WordPress or Your application where you want to point Sub-domain.</li>



<li>Click on create.</li>
</ol>



That’s it you have created wildcard Sub-domain.

Create Wildcard Sub-domain from your hosting panel / cPanel

Today I am&nbsp;in big trouble I want to take&nbsp;emergency backup from&nbsp;client-server to another server, this is not actual problem main problem is the size of data and its more than 50 GB and I don’t want or any one don’t want to download and upload huge&nbsp;data from server to&nbsp;local machine and again on server.



I have found one solution to copy data from one server to another without downloading any file you just need SSH access of both server.



I am going to explain you Linux&nbsp;SCP command to copy file from remote&nbsp;server to local machine or on another server.



scp&nbsp;copies files between hosts on a network. It uses&nbsp;ssh&nbsp;for data transfer, and uses the same authentication and provides the same security as&nbsp;ssh.&nbsp;scp&nbsp;will ask for passwords or passphrases if they are needed for authentication.



<pre class="wp-block-preformatted">[root@xxxxxxx public_html]# scp -r root@xxx.xxx.xx.xx:/home/userdirectory/public_html/upload/ .</pre>



<ol class="wp-block-list">
<li><code>scp -r</code> will copy your directory recursively.</li>



<li><code>root</code> is the username of old server.</li>



<li><code>xxx.xxx.xx.xx</code> this will be server IP address or you will also connect by using domain name.</li>



<li>After colon : you need to mention server static directory path which you need to copy.</li>



<li>Last . (dot) use for current directory of new server, if you want to use another directory you need to mention static path of server directory.</li>
</ol>



if you check the option for SCP command you will get



<pre class="wp-block-preformatted">-P port Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already reserved for preserving the times and modes of the file in rcp(1). -p' Preserves modification times, access times, and modes from the original file. -q' Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1). -r' Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal. -S program Name of program to use for the encrypted connection. The program must understand ssh(1) options. -v' Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems. The scp utility exits 0 on success, and &gt;0 if an error occurs.</pre>



if you want to exclude some files to copy on new server Linux scp command is the best way for you, if you want to all file without excluding any file from server then we have easiest way more than this it’s WGET. Read more about WGET.

Here we have talking about a vary small part of website, But it’s most important in your social or online presence.



All search engines have there own Crawlers, Crawler or Search Engine Robots it’s automated script which is grab data from your website and show it too user. When users are try to find or search relevant data which you have published on your website, they have find your website name in a search result with your published data.



Now this is the most important part, which part you want to show when users are searching over internet.



Crawler first fetch the information from robots.txt then crawler go to crawl sitemap. In Sitemap your all website links are stored which you are decided to indexed with search engine.



But what crawler do with other sensitive directory and links which is available on your server?



Crawler is a script, it doesn’t know which is your sensitive data or which is not. Script will do work as they design for.



You need to block your important directory or links from crawler to stop crawling important data.



Here is one example of robots.txt to prevent to Crawl important directory of WordPress and some part of important data or scrap data which you don’t want to publish over internet.



<pre class="wp-block-preformatted"># Below mention disallow paths are important to block from search engines

Optimize your WordPress by upgrading robots.txt

In this post I have mention the code for .htaccess file, this will help you to improve your page speed and SEO ranking.



The basic WordPress .htaccess file have basic URL rewriting rules



<pre class="wp-block-preformatted"># BEGIN WordPress
&lt;IfModule mod_rewrite.c&gt;
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
&lt;/IfModule&gt;
# END WordPress</pre>



Now we will start to optimize your wordpress site



Step 1: leverage browser caching



<pre class="wp-block-preformatted">## EXPIRES CACHING ##
&lt;IfModule mod_expires.c&gt;
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType text/html "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
&lt;/IfModule&gt;
## EXPIRES CACHING ##</pre>



Step 2: Compress Your page content



<pre class="wp-block-preformatted">&lt;IfModule mod_gzip.c&gt;
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
&lt;/IfModule&gt;</pre>



Step 3: Compress Your HTML



<pre class="wp-block-preformatted">function sanitize_output($buffer) { $search = array( '/\&gt;[^\S ]+/s', // strip whitespaces after tags, except space '/[^\S ]+\', '&lt;', '\\1' ); $buffer = preg_replace($search, $replace, $buffer); return $buffer;
}
ob_start("sanitize_output");</pre>



add this code into your theme&nbsp;<code>index.php</code>&nbsp;file.



this will definitely help you to increase your page speed.

WordPress .htaccess file – SEO optimized

How to improve page speed or page loading time? This question lots of time ask and search online. Reason behind this question is, today we have used lot’s type of web font, different type CSS to look and feel and in now days CSS Transitions on your website and the vast area cover by java script for animation and other use.



In this situation we can not remove Java Script, CSS or Image from our website. We need to find some solution on this problem. We will solve this problem by caching your CSS, Java Script or images which is not change regularly.



We need to remember When you are writing content or adding images in content, images must be minifyed and content is not more than 250KB as per SEO rules.



Now i will have some code to leverage cache and minify your HTML on the fly.



Keep maximum your Java Script, CSS, Images expiry time this will effect on you Page Load Speed (PageSpeed) and increase by 20%, But keep in mind your uploaded images is always compressed and its not more than 120 kb or 180 kb.



<pre class="wp-block-preformatted">## EXPIRES CACHING ## &lt;IfModule mod_expires.c&gt; ExpiresActive On ExpiresByType image/jpg "access 1 year" ExpiresByType image/jpeg "access 1 year" ExpiresByType image/gif "access 1 year" ExpiresByType image/png "access 1 year" ExpiresByType text/css "access 1 month" ExpiresByType text/html "access 1 month" ExpiresByType application/pdf "access 1 month" ExpiresByType text/x-javascript "access 1 month" ExpiresByType application/x-shockwave-flash "access 1 month" ExpiresByType image/x-icon "access 1 year" ExpiresDefault "access 1 month" &lt;/IfModule&gt; ## EXPIRES CACHING ## &lt;FilesMatch "\\.(js|css|html|htm|php|xml)$"&gt; SetOutputFilter DEFLATE &lt;/FilesMatch&gt; &lt;IfModule mod_gzip.c&gt; mod_gzip_on Yes mod_gzip_dechunk Yes mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$ mod_gzip_item_include handler ^cgi-script$ mod_gzip_item_include mime ^text/.* mod_gzip_item_include mime ^application/x-javascript.* mod_gzip_item_exclude mime ^image/.* mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* &lt;/IfModule&gt;</pre>



Above code will affect on your Java Script, CSS, Image, PHP and on HTML and increase you page speed.



Now Below code is my favorite it will compress your HTML and decrease HTML page loading time.



<pre class="wp-block-preformatted">function sanitize_output($buffer) { $search = array( '/\&amp;gt;[^\S ]+/s', // strip whitespaces after tags, except space '/[^\S ]+\&amp;lt;/s', // strip whitespaces before tags, except space '/(\s)+/s' // shorten multiple whitespace sequences ); $replace = array( '&amp;gt;', '&amp;lt;', '\\1' ); $buffer = preg_replace($search, $replace, $buffer); return $buffer; } ob_start("sanitize_output");</pre>



Place above code in your index.php or the root PHP file which run first when your template or page will be load.
