Introduction to the Series 40 web apps Platform

Ovi Browser

Ovi browser (Ovi browser) is a distributed Web browser designed for devices with limited processing capabilities and memory, such as Series 40 mobile phones. Like other browsers, install an Ovi Browser Client on your mobile phone). At the same time, an Ovi Browser Proxy server named Ovi Browser exists on the Nokia network). This proxy server is responsible for processing most of the operations previously required to run on mobile phones, and also for proxy communication between the Ovi browser client and the website. The proxy server transmits the optimized content to the mobile phone, which reduces the network traffic and the calculation of the mobile phone.

The software developer creates a Web App through Nokia Web Tools, and then tests the Web App on the simulator and Series 40 real machine respectively. After the application is completed, it needs to be uploaded to the Ovi app store. You can download and use the Series 40 mobile phone.

Operating Mechanism

1. After a mobile phone user opens a Web App, a network connection is established between the Ovi browser client and the Ovi browser proxy server.

2. The Web App runs on the proxy server. If the Web App contains any scripts, run these scripts. The Web App connects to the application server on the network or other data sources as needed. Then, the results and data are sent to the client. The data includes HTML, CSS, images, and other information.

3. After receiving the data, the client displays the data on the screen and interacts with the user.

4. for most Web apps, you can enter some information such as the user name and password. Generally, the data is sent to the proxy server, and the proxy server is responsible for processing the data.

5. After the proxy server processes the data, it returns the result to the client on the mobile phone. The returned data may be a brand new page or partially updated data. If it is the latter, only the changed data is returned to reduce the data traffic.
