Hi.

There seems to be an issue with the browser cache of the BlackBerry 9000.
Some images get broken if the server sends a "304 not modified" response.

Steps to reproduce the problem:

Create an XHTML page with an image on it which has an expiration time of 60 seconds (for example with apache mod_expires)
On the page place a link to itself.
Open the browser, clear the cache and history
Open the page via the "Go To..." menu entry
Page and image is displayed properly
Wait >1 minute, click the self link
The browser sends a request and adds an "If-Modified-Since" header
The server answers with "304 Not Modified"
The image is broken now

Tested devices:
T-Mobile, Web&Walk Browser, BlackBerry 9000,, v4.6.0.92 (Platform 4.0.0.117)
Vodafone, Internet-Browser, BlackBerry 9000, v4.6.0.125 (Platform 4.0.0.134)

This cannot be reproduced using the simulator.

Any idea?

Thanks.

What browser are you testing with, the BlackBerry Browser (BlackBerry Enterprise Server), Internet Browser (BlackBerry Internet Service) or WAP Browser (carrier's WAP Gateway)?  You can check your default browser setting by going to Options, Advanced Options, Browser.

Hi,

On the first device the browser is called "web'n'walk" which I think is an alias for the Internet Browser

The browser of the second device is called "vodafone live".

Thanks

the Web'n'Walk is the browser that uses the T-Mobile proxy. http://www.webnwalk.co.uk/
the "Vodafone Live" is the browser that uses the Vodafone UK proxy.

Hi,

I also verified this problem with an Orange UK device v4.6.0.125 (Platform 4.0.0.134)
Browser Configuration: "Internet Browser"

best regards

Do you happen to have a publicly facing test URL that demonstrates the issue?
