How to configure the cache validity time of files downloaded from KM?

Dear Guru's,

I need your help on the following. We currently have a KM Navigation iView inplace that allows some endusers to download pre-calculated and generated reports that are Zipped from KM.

When clicked on the default browser behaviour is that the browser (MSIE) will confront the user with a popup that allows:

1. Save File to disk

2. Open the File

3. Cancel

This is ok. Most users will click "open the file" this will actually download the file to the "Temporary Internet Files"-folder and then open WinZip on this file. The WinZip dialog then shows the Excel file. This can be opened, saved or whatever...

Here it comes... when the initilal zip file is opened instead of saved to disk then as mentioned it is stored in the temp internet files.

All files stored in temp internet files most of the time have an Expires property set. This is the Cache validity.

But the ZIP file as mentioned in the example doesn't Expire as it is set to not expire at all. This will give unwanted behaviour as the zip files will be refreshed weekly or montly on the KM server and then the when the user wants to get the latest the browser will take the file in the Cache instead of the KM server.

How do I set the cache validity periode for KM files? Or KM in general?

Ansers like:

- Clear Temp Internet files

- Let users always save instead of open

... will not be awarded

Thanks in advance,

Benjamin Houttuin
