BlackBerry Browser features

The BlackBerry Browser provides features that can accommodate the constraints of mobile devices and wireless

networks to make mobile browsing efficient and user-friendly.

Feature Description

Web content

support

The BlackBerry Browser supports a wide range of web content, including

• Markup: Compact HTML (cHTML), HTML, XHTML Mobile Profile, WML, and SVG

• Images: GIF (GIF87a and GIF89 – static only), WBMP, PNG, and JPEG

• Scripts: WMLScript and JavaScript™ (JavaScript 1.3 and earlier; subsets of JavaScript 1.4

and 1.5; and the ECMA-262 ECMAScript Language Specification)

• Media: SVG-based interactive media and animations

Background

requests

Browser requests can run in the background, so users can continue to view other web pages

or use other applications while the web page is loading.

Pending or

offline content

If users are outside of a wireless coverage area, they have a number of options for managing

web content requests:

• When a web page request cannot be completed, the user can save the pending request

to the Messages screen. The BlackBerry Browser resends the request when the

BlackBerry device is in a wireless coverage area and can notify the user when the page

is available.

• Users can define bookmarks for offline use, so they can view cached content without

retrieving it from the server again.

• Users can fill out offline forms and have the BlackBerry Browser queue and submit the

forms in sequence when the BlackBerry device is in a wireless coverage area.

Integration with

BlackBerry

device

applications

The BlackBerry Browser integrates with other BlackBerry device applications to provide a

consistent user experience. Users click a URL in an email message to view that web page in

the BlackBerry Browser. The BlackBerry Browser recognizes URLs, email addresses, and

phone numbers in web pages, so users can click a link to open a new web page, compose an

email message, or place a phone call.

Content

optimized for

wireless

browsing

The optimization service optimizes web content for wireless browsing:

• Image optimization: Depending on BlackBerry device capabilities, the optimization

service converts .jpeg, .gif, .ppm, and .pnm images to .png images, scales images to fit

the BlackBerry device screen dimensions and reduces color depth.

• Content filtering: The optimization service processes HTML content to remove

unsupported tags, converts data to a tokenized format, and compresses the data for

efficient delivery over the wireless network.

• Page rendering: The optimization service retrieves images while it is processing HTML

or XHTML content. It includes the images with the pages that it sends to the BlackBerry

device for faster browsing.

Data security All web browsing between the BlackBerry device and the corporate network occurs over the

standard encrypted connection through the connection service. The BlackBerry Enterprise

Server provides this data security out-of-the-box, without substantial additional setup.

The browser supports the standard SSL and TLS protocols for additional security, especially

to servers on the Internet. By default, if SSL or TLS is requested, the connection service

creates a proxy SSL connection on behalf of the BlackBerry device to make browsing faster.

Users can choose an end-to-end SSL connection. System administrators can set a policy to

enforce end-to-end SSL.

The BlackBerry Browser supports JPEG images only on BlackBerry devices with color screens. For BlackBerry devices with monochrome

screens, the BlackBerry MDS Data Optimization Service converts JPEG images to PNG format.
