I've used Exponential to generate KML files for Google Earth. To achive this I've made a new pagelayout (kml_pagelayout.kml) and some template overrides (kml_view.country.tpl etc).

You'll find an example on:
http://www.globalis.no/land/afghanistan

Click on the link "Vis land på Google Earth"

This is working with Firefox but Internet Explorer gives an error:
"Could not open file..."

This is a known error and is not directly connected to Exponential:

I've tried different solutions but it's still not working.

Does anyone have a solution???

Hi Bjørn

This has probably something to do with cache control.

I've encountered the problem before with other types of files and I used the following HTTP headers to solve it:

Expires: 0
Cache-Control: private
Content-type: application/x-Research-Info-Systems
Content-Disposition: attachment; filename="export.ris"

Thanks for your reply.

Is it possible to set these HTTP headers without changing the kernel files of Exponential?

SOLVED!

I had to add these lines to site.ini.append.php:

[HTTPHeaderSettings]
CustomHeader=enabled
HeaderList[]=Cache-Control
Cache-Control[]
Cache-Control[/layout/set/kml]=private

It is now working in both Internet Explorer and Firefox

Thanks for your help.
