HTTP GET file download fails with "Alert, An unknow&quo

[Guest bkuehl]

Hello,

With a Smartphone 2003 device I browse (using GPRS; the device is not in the cradle) with the IE to an html page which contains a link like

<a href="xxx.cab" type="application/x-cab-compressed">xxx.cab</a>

When I select this link my device does a HTTP GET and after this presents me a panel where it asks "Download the xxx KB file xxx.cab?". It seems that the device does the HTTP GET just to collect the filename and file size from the HTTP response. When I now select yes the device tries to start a second HTTP GET to download the file.

Sometimes the second HTTP GET does not make it to the web server and the device just raises an "Alert, An unknown error has occurred" panel.

One idea is that the GPRS provider uses a proxy and sometimes returns a 304 HTTP status code for the second GET. Can this the problem? If yes how do I solve this? If no do you have an idea where the problem is?

Thx,

Bernd
