Q. I'm using Cookie-protected directories over an SSL connection and I cannot download zip files (or Save-target-as) with Internet Explorer (Netscape works fine). (.pdf, .xls, .doc, .zip, .exe).

A. Normally AuthentiX sends a pragma-no-cache with each file that is served in a cookie-protected directory - if you have cookie-timeouts set, then this will ensure that a page will not be cached in the browser and available for viewing after the timeout has expired. With SSL and IE trying to download a file, this causes a problem and you need to switch the pragma-no-cache off.
(For IIS6 this now also seems to be true for .exe files.)
With SSL, the default setting for all browsers is not to cache pages from SSL encrypted sites, so the pragma header is unnecessary anyway .

To switch the pragma-no-cache off add a value in the registry, using regedt32.exe,

HKEY_LOCAL_MACHINE
	/Software
	/Flicks Software
	/AuthentiX
	/1.0
	/AuthentiXConfig
of type REG_DWORD with the name CookieStopNoCache make its value 1 to stop the no-cache.
Then stop and restart IIS Admin Service (IIS4/5 and above) or World Wide Web Publishing Service (IIS3) from the control panel.

Other options are CookieStopPrivate, to stop the "Cache-control: private", and CookieStopExpires, to stop "Expires: 0"

One user reported that hitting the back button after submitting a form in Netscape resulted in:

Data Missing
This document resulted from a POST operation and has expired from the cache. If you wish you can repost the form data to recreate the document by pressing the reload button.

To remove this message he used the following options:
CookieStopExpires 1
CookieStopNoCache 1
CookieStopPrivate 0
