Valid Values are:
0 - Disabled (attachments and images may be left behind in the browser's cache if user does not logout)
1 - Enabled (documents are not cached)
This vartiable is new in 6.5.4
SPR# HTAA68YA56 - When not using an ActiveX attachment utility, a tiff file attachment is unable to be viewed. Setting "INOTES_WA_OPENELEMENTNOSTORE=0" in Notes.ini fixes the problem.
SPR# PTUL62HAYE - An imbedded image could only be saved as a BMP in Domino Web Access. The default behavior (no ini variable) will be to emit cache-control: no-store response header for all DWA ?OpenElement URL commands which are not directed against iNotes6.nsf (etc). This default will ensure that attachments and images from a user's mail file are not left behind in the browser's cache.
This behavior has, however caused a side-effect, reported in SPR PTUL62HAYE, which is caused by an IE bug, and therefore the Notes.ini variable "INOTES_WA_OPENELEMENTNOSTORE=0" will disable the behavior of preventing the documents from being cached. If "INOTES_WA_OPENELEMENTNOSTORE=0 is set, Administrators should train their users to always logout of DWA, so that the DWA ActiveX control will remove the browser cache at that point. The "no-store" option is intended to prevent caching of attachments and embedded images, even if the user fails to logout.
