Tricks to reduce javascript load time in webpage

Javascript is plays important role in any web based application.But some times javascript also lead to slowness in the webpages. In order to improve java-script performance we can use following techniques.

1. Add all the javascripts in the bottom of the page instead of adding in the head.
2. Try to combine all the javascripts functions and include through external file instead of including all scripts in main file.

<script       src="ourscript.js"></script>

3. We can minimize the javascript we are using in the application. This will reduce the load time as much.

4. We can also enable  asynchronously down the load script,this option improves the DOM construction during webpage load.

<script   async="async"    src="ourscript.js"></script>

Automatic HTTP to HTTPS redirection in Tomcat

Automatically we can redirect non secure HTTP URL to secure HTTPS URL in tomcat. Any web application to secure the data transfer use to configure https access. Some times even after setting up the https access default http access also available along with https. This could a security thread for the application.

Assuming your already configured HTTPS access for the application , Now we need do the change web.xml in tomcat under apache-tomcat-8.0.36/conf/web.xml to redirect all non http access to https.

<!-- Added to redirect http to https -->
<security-constraint>
<web-resource-collection>
<web-resource-name>Whole Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>

Now when we access http://localhost:8080/myapp it will be redirected to https://localhost:443/myapp

Telnet test simulation in Unix and Solaris

Simulating telnet test in Linux ans Solaris is very easy. NC tool used to simulate the telnet test,We do telnet test to validate the connectivity between two machines.Telnet test gives us information mainly host and port are accessible from another machine. In order to validate this service should be running on specific port in other machine and in case this not running how can we simulate the port accessibility?

If the service is already running on specific port we can do the telnet test as like below.

telnet 128.25.65.12 8090

Now if the service is not running how to simulate telnet behavior?. This can be achieved by using 'NC' utility in linux/solaris. To simulate telnet first we need login destination machine and we need to start the system in listening mode as like below.

nc -l 8090

Once destination machine is started in listening mode, We can hit telnet test as mentioned abouve.
