Varnish Web Cache Application Evaluation

Websites today have static and dynamic contents that concern many people about the performance. People will leave or not returning the website because of loading time that is taking too long. One way to speed up a website access is by utilising web applications using Varnish cache. Varnish will store static content from a website in the memory. Static data is data that changes infrequently or rarely updated. A front end for web administrators was built for Varnish application so that the configuration can be done easily. The configuration that will be simplified through the front end of this Varnish application is detecting SQL injection and Cross Site Scripting (XSS), block files and folders, HTTP header manipulation, detects the original file whether it is deleted or blocked and error handling configuration. The front end application is implemented on Linux platform. Varnish application was tested using ApacheBench where the number of requests from the client and the response time become the main parameters of the test.
