Cacheability issue with IE

[ashish]

hi All,
I have a web page which tries to send user a file attachment using
httpresponse, by setting the content-Disposition header..

the problem is that the page is hosted on a ssl site, and there is a
issue with IE that it wont download files where Cache-control header is
set to no-cache.

My problem is that even if i set page cacheability on the event handler
of the button, the response still contains 'Cache-Control: no-cache'
header..

for some other reasons in the application, the base class of the page
sets the cacheability to no cache,

can i not change the cacheability on the event handler, can it be set
only once ?

i tried using response.ClearHeaders, but its still same...

regards

Did you ever figure this out? I am having the same problem and I have tried
everything. The downloads work fine under HTTP but under HTTPS I get an
error on certain machines. On other machines including a Mac work fine.

I think the following solved the issue for me.

One of the Advanced settings in the IE options is "Do not save encrypted
pages to disk" I had this option checked and I believe this is why neither
download (attachment) nor open (inline) worked under HTTPS / SSL for me.

What error message do you get?
