iis - My Application.cfc logs me off when I click a link after initial login has any seen this error? -

my website using iis , coldfusion. reason when log site, click link or button cfm page located in same secure directory send me login. if login again not prompt me again session.

i have read on other post may have fact default page in iis index.cfm , when entering secure directory without defining page sent index. strange think alright.

my default page when entering admin directory index. included below application coldfusion component.

has had problem occur?
