When i view an image from Nirvanix, the image cannot be cached in temporary folder. That means everytime I press the Refesh button, the page always try to load images over and over from Nirvanix which is quite inconvenient. I've checked and see that the Expires in Temporary folder of those images are 1 hour ahead of the current time (my timezone is GMT + 10:00). Is there any way to set the Expires to None?

Also, I tested to view an image from S3, the Expires of the image is None. So it could be from Nirvanix side??? How can I overcome of this??

A few questions, what are you using to do the download?  Expiration currently is managed by the e-tag.  Can you provide specific headers so we know exactly what the failure is?  I have verified the cache locally and everything seems to be in good order so any information you can provide will be very helpful in determining the problem.

I put this line of code in the .aspx file (normally I dont need to do this):

<%@ OutputCache Duration="999999" VaryByParam="none" %>

I have tested with IE and Firefox after I cleared cookies and everything:

1. Firefox:

It looks OK as I can't see it's loading 10 pictures or more, it responds quite fast so I assume it reads these pictures from its cache.

2. IE

I can see clearly it's loading and sometimes it's quite slow to display all the pictures. I checked the temporary folder of IE and see that all pictures from Nirvanix have been cached but the Expires is always be set 1 hour ahead of the current time, whereas the other pictures from other sites is None.

Can you help???

 Thanks for this information, please let me know the exact version of IE since version 6.0 has quite a few bugs with caching which we return custom headers for.  Every version of IE has its own issues and can behave strangely even when given correct headers.
