Notes/Domino 6 and 7 Forum : HTTP Image Caching

Hi - I hope someone can help with this problem....

We use Infosys' Web Content Management system ('Domisphere') to host our web site.

The pages are fairly graphic intensive and in the Domino 5 version, they seemed to cache correctly on the browser (loading instantly on any subsequent pages that shared the same graphics).

However, in the new Domino 6 test version, all images reload every time we load a page, or even refreshing the same page (you can see the 'Downloading picture...' message for each one in the status bar as it loads even on a lan connection). They are all gifs or jpgs accessed through the <img src....> tag and stored on the Domino server's file system.

I assume this is a Domino 6 change to the cacheing options? I have tried creating a website rule which sets the expiry date for /*.gif, and this does indeed set the expiry date to the future (if you view the temporary internet files in IE), however, the images are not taken from the cache, but still reloaded.

This is a serious problem for us and may make us reconsider moving to Domino 6 as the performance hit for our web site clients could be significant.

Has anyone any ideas on solving this?

Regards and thanks in advance
