A method for increasing interaction speed between a website and a client device includes storing on an HTML5 local storage database on the client an ECMAScript file and a parameter from a web server of the website, and subsequently comparing a web server version number of the ECMAScript from the web server with the local version number of the parameter stored on the HTML5 local storage database. The parameter specifies a local version number of the ECMAScript file. The method can also include updating the ECMAScript stored on the HTML5 local storage database with the ECMAScript file from the web server when the web server version number is greater than the local version number. The method can also include loading the website on the client by retrieving the ECMAScript file from the HTML5 local storage database. Retrieving the ECMAScript file from the HTML5 local storage database can occur when the web server version number is the same as the local version number. The method can also include loading the website on the client by retrieving the ECMAScript file from the HTML5 local storage database.
